"I can see FOREVER!"An image that contains a smaller replica of itself, which (being a replica of the image) contains a smaller replica of itself, which contains ... well, you get the idea. Like a fractal, but without all the complicated math. The more formal name for this is "infinite regression". For instance, take this cover of Spoof which shows the characters holding a copy of that very comic, whose cover depicts them holding ... a copy of the very same comic (with the same cover). Theoretically, there could be infinite recursion of that comic book in the image, though it's safe to assume that the printer doesn't have enough resolution to reproduce them all. (It's the thought that counts!)note A similar effect can be set up in a Hall of Mirrors by putting two mirrors facing each other. See also Nested Stories and Dream Within a Dream, which has the layering but not the self-similarity. Also see Recursive Reality which is this trope on a cosmic level.

- The final shot◊ of Owarimonogatari's first opening.
- Thoth from Part 3 of JoJo's Bizarre Adventure is a comic book which depicts events in the near future that are guaranteed to happen, but heavily subject to Prophecy Twists. The zenith of this occurs when it shows what appears to be bullets going through Jotaro's head, but turns out to be bullets going through a picture of Jotaro's head—so it turns out any of Thoth's prophecies might be depicting it's own pages in the future.
- M. C. Escher's "Print Gallery"◊ is a very unusual take on this concept: It only shows one copy of the picture, but implies an infinite recursion all the same, using uneven magnification to make the contents of the picture merge with their real-world analogues.
- The Dutch mathematicians Bart de Smit and Hendrik Lenstra calculated that the blank area at the center would contain a copy of the original picture (scaled down by a factor of 22.5 and rotated by 158 degrees), and created a version where the blank area is filled (as well as many variants thereof with different curvatures).
- Cassandra Calin's drawing of her stealing her drawing.
- In comics, it's called an infinity cover.
- An issue of Runaways has Victor, a cyborg who was (unknowingly) being used to spy on the team, discover the TV screen where the camera in his eyes feeds back to.

- From the My Little Pony: Friendship Is Magic fandom:
- An infinitely zooming picture of Apple Bloom getting a picture of herself as her cutie mark.
- This picture of Twilight Sparkle drawing a human, who's drawing Twilight Sparkle, who's drawing a human. It doesn't extend infinitely, because each inner picture is less finished than the one drawing it.
- In fact, anything on Derpibooru with the "droste effect" tag would apply here.
- This effect is captured in Citizen Kane when Kane passes between two mirrors.
- Orson Welles, the director of Citizen Kane, did this again in The Lady from Shanghai in a Hall of Mirrors sequence.
- In Spaceballs, the titular bad guys watch the Spaceballs video tape to find out where the heroes are. Hilarity Ensues when they get to the exact point in the tape that they are in, although the Droste effect is too small to see much of.
- Happens in The Matrix Reloaded with the architect: The room's wall is filled with monitors depicting Neo in the room (and his various anticipated reactions), which in turn are rooms with monitors across all walls. There are several transitions where the scene zooms in on whichever monitor corresponds to Neo's actual reaction.
- While not in the film itself, the box art◊ for Memento.
- Airplane! uses this when the air traffic controller, McCroskey, adopts a thoughtful pose in front of a framed photograph of himself holding the same pose. Airplane II: The Sequel then cranks this Up to Eleven by posing McCroskey in front of a framed photo of himself posing in front of the framed photograph of himself.
- Happens to Doctor Strange during his trip through the Multiverse, as he nears Dormammu.
- Escape from the Planet of the Apes uses this as a metaphor for Time Travel: A painting that contains an infinite regress of images including the painter himself.
- In Hot Fuzz, the shot of Simon Skinner's smiling face in front of a photo of himself smiling◊. A more easily missed example occurs in the very first shot of the film, when Nicholas Angel marches up to the camera and, scowling, holds up his badge, which has the same scowl. Both shots were made by copying a frame from the film and pasting it onto the photo, so these are true droste images and not just similar.
- Biff in his office in Back to the Future Part II, standing in front of a painting portraying him in a similar pose.◊
- The Hobbit trilogy:
- In The Desolation of Smaug, after Gandalf is beaten by the Necromancer a.k.a. Sauron, the Necromancer appears as the Eye of Sauron with the pupil in the shape of his humanoid form, itself with a single flaming eye, repeating infinitely from within.
- Later used to represent Sauron's battle of wills against Galadriel in The Battle of the Five Armies, with the camera at first zooming further and further into the image; as Galadriel gains the upper hand, the constant zoom slows, then begins receding.
- At the end of All About Eve, when Eve has supplanted Margot and has a Loony Fan/Stalker With a Crush of her own hanging around her hotel room, the fan tries on her cape and poses in front of the mirrors holding the award Eve has just won, and a shot of hundreds of images of her from all angles indicates that the cycle is endless and there are infinite Eves out there.
- Dep. Chief Hardy in 22 Jump Street has a photo hanging on the wall behind his desk—of him sitting at his desk, in the exact same position he's in when the camera catches the photo.
- In Nine Miles Down, the protagonist has a (possibly hallucinatory) encounter with this trope, in which every other reflection is a deformed Mirror Monster version of himself. Made far more disturbing when the most distant reflections start shooting themselves in the head, in a wave of suicides that rapidly gets "closer" to the actual character.
- A magic-induced variation appears in Harry Potter and the Chamber of Secrets. The fraudulent, highly decorated wizard Gilderoy Lockhart has a portrait of himself in his classroom at Hogwarts...actively painting another picture of himself. Additionally, in Harry Potter and the Order of the Phoenix, the cover of the textbook Dark Arts Defence - Basics for Beginners (which replaces Defensive Magical Theory from the original book) features a young witch and wizard surrounded by black cats and reading a copy of the book with the cover facing out.
- The poster for Toys.
- "Jack's Story" from The Stinky Cheese Man could be considered a print version of this, as it features an infinite regression of the same story nested inside itself. Justified in that he's (Jack, that is,) telling this story to a giant who intends to eat him after he finishes his story. So he tells a story that can be continued for an infinite amount of time, or at least until the giant falls asleep. Which he does. On a later page, we see Jack making a break for it.
- In The Mouse and His Child, much is made of a particular dog food label depicting a Droste Image of the dog holding the same can, complete with the same picture, continuing down ad nauseam. It's said that some grand revelation lies beyond "The Last Visible Dog", i.e. the smallest iteration that can still be seen.
- The cover of the Little Golden Book My Christmas Treasury features a little boy and girl, and a cat and dog, sitting on a rug, reading a copy of the same book which features a little boy and girl, and a cat and dog, sitting on a rug...
- The Ramona Quimby book Ramona Forever gets its title from a scene where Ramona does this with the angled mirrors in a dressing room.
- In Equal Rites, Simon conjures an image of the Discworld which is amazingly accurate, right down to an image of Simon conjuring an image of the Discworld, and so on. Esk is also fascinated by this effect when cleaning a bathroom in the University; she has an uneasy feeling that one of the multiple reflections, in the very edge of perception, is waving back at her.
- Paired mirrors that create this effect are a plot element in Witches Abroad.
- In The Art of Discworld, Paul Kidby's drawing of Dr Whiteface shows him holding a marotte tipped with a whiteface clown that's holding a marotte, and so on and so on.
- The Peter David Star Trek novel I, Q featured Picard, Q, and Data moving through a Hall of Mirrors. Data naturally stops and stares when two mirrors create such an image. Q can't resist asking him how many reflections he sees...then cuts him off when he starts in the trillions.
- In A Song of Ice and Fire, the Noble House Risley uses the arms: "A black knight on a black rearing horse on white, bearing a golden lance and a white shield, upon which is seen the above in miniature."

- The book of The Neverending Story was about a book which became the literary version of this trope, when the person writing the book was ordered to read the very same book they were writing, and they had to keep writing what they were reading while they were reading it, making the story literally never-ending (hence the title). The endless loop can only be broken by Bastion accepting that he can take control and change the story.
- The first episode of The IT Crowd opens with one of these: A shot of Mr. Reynholm at his desk, with an identical scene on a picture hung on the wall. The camera then pans out to reveal another identical scene. When he starts talking, we see that we were actually looking at the picture on the real Mr. Reynholm's wall.
- Square One TV did something similar to teach viewers the concept of infinity.
- During Steve Martin's "I'm Me" song on Saturday Night Live, he notices a monitor showing live footage of him, thus creating this effect. "It's me, watching me, watching me!"
- In Kamen Rider Decade, Decade's Transformation Sequence into his Complete Form invokes elements of this. Decade has a card of himself in Complete Form located on his forehead. Which has a card of that on its forehead, and so on. The sequence repeatedly zooms in on Decade's forehead of infinity until he's suited up.
- An episode of Happy Endings had Jane doing a slide presentation of her father's interests, one of which was "old-timey slide projectors." The accompanying visual was somewhat unsettling...
- In the end of an episode of Rutland Weekend Television, one of the announcers is reading the credits for the show. The credits in the script he's reading stop around a certain point, however, so he runs up to a television monitor showing the show so he can read the credits on the screen out loud instead. The monitor, behind the credits, shows him reading from the screen which, behind the credits, shows him reading from the screen...however, he doesn't read quickly enough. Hilarity Ensues.
- Stephen Colbert's portrait on The Colbert Report slowly became one of these, as every season he had a new portrait painted... where he posed in front of the previous portrait. That said, what he's holding, generally his latest book, is different. In the final episode, the portrait is completely empty.
- In an episode of Mad Men, Sally and Glen (kids) have a Seinfeldian Conversation where she points out this is the case with the Land o' Lakes butter label, and says it scares her.
- In one episode of the live show MTV's Most Wanted in the mid-1990s, the camera followed presenter Ray Cokes through the lobby of the MTV Europe studios, where there was a video wall showing the current program on MTV Europe. Pointing the camera straight at it, this produced a Droste image of that video wall, which was then enhanced by the cameraman (probably Rob the Cameraman) rolling the camera left and right, the image following this with a slight delay for each iteration — giving the impression of a kind of moving tunnel.
- Modern Family does this to go from the Cold Open to the opening credits.
- An old CBS logo, seen for instance at the end of The Twilight Zone, features a push-in on a CBS eye inside a larger CBS eye.
- An unintentional example happens every now and then on Pardon the Interruption when the hosts ask Tony Reali whether they made any mistakes. The monitor at Reali's desk shows the camera feed, and that screen has a smaller version of the camera feed, and so on and so on.
- The classic Doctor Who title sequences were created using this effect. The producers made the original (Hartnell to early Pertwee) sequences by pointing a camera at its own monitor and then passing objects across the lens to create the weird "howl-around" feedback effects.
- The NuWho Series 8 of Doctor Who (not to be confused with the 1971 Season 8) returns the use of the Droste Effect to the title sequence by having the TARDIS fly out of and into a spiral Droste clockface.
- In the episode "Sleep No More", when the Doctor is demonstrating that the villain is pulling images out of Clara's eyes, he projects the image into its own field of view, producing this effect.
- Abby from NCIS gets to enjoy one courtesy of her spy glasses and a monitor showing her the video feed. "Whoa...trippy..."
- Tyler Perry, announcing for an episode of Best Time Ever With Neil Patrick Harris, does such a good job that he writes a book during the commercial break about announcing. He holds up the book, with cover art featuring Perry holding the book, with cover art featuring Perry...

- In The Flash (2014) episode "The New Rogues", Barry weaponizes this to defeat Sam Scudder/Mirror Master. Sam has the power to use mirrors as portals, but when Barry arranges several mirrors to create this effect, when Sam tries to escape through one, he just ends up back where he started.
- An issue of Dynamite magazine had a Droste cover featuring Jimmie Walker.
- The Christmas 2008◊ cover of the Radio Times shows Wallace & Gromit reading that very issue of the Radio Times.
- #400◊ of Doctor Who Magazine shows David Tennant reading that issue of DWM (a reference to an image in #1 of Doctor Who Weekly which showed Tom Baker reading the magazine - but which was not itself a Droste image since Tom's copy wasn't on that page). This was reprised in a photoshoot for #500 which had Peter Capaldi reprising all the Milestone Celebration covers.
- Science mags are naturally a fan of this trope. An example from a less expected area - chemistry.
- The last scene of The Smashing Pumpkins' "Ava Adore" video.
- The New Pornographers use TV monitors to create this effect in their video for "Letter From An Occupant."
- The cover of Pink Floyd's Ummagumma uses a variation: a photo of the band with a smaller photo on the wall containing a smaller photo containing a smaller photo. However, each successive photo shows the various band members occupying each other's places.
- The album cover for Best of Friends - The Smurfs.
- Used on the cover for Big Country's 2001 covers album Undercover
- The album cover for Amber Gambler by Gorky's Zygotic Mynci.
- The album cover for Swing to the Right by Utopia.
- The video for The White Stripes' Seven Nation Army.
- The video feedback method referenced below is one of the special effects used in the music video for Queen's Bohemian Rhapsody.
- The music video for "I'm Gonna Always Love You" (Baby Piggy's song from The Muppets Take Manhattan) has a number of moments where a scene revealed to be on a TV the Muppet Babies are watching. Inevitably, this leads to a moment when the scene of them watching TV does this, and they turn to the camera trying to figure out what's going on.
- Dean Ambrose finds a wired, fully turned-on flat-screen monitor under the ring at Tables, Ladders, and Chairs 2014. Before he uses it as a weapon, he stares at it, grinning like a maniac, while a cameraman looks over his shoulder at Dean and the monitor, intentionally invoking this kind of image. But then the scene cuts to the array of giant ladders towards the stage, giving him an insidious idea. He'd use that monitor later, but it was gimmicked to explode when the cord was pulled on too hard, eventually costing him the match.
- Every year, ESPN The Magazine has an issue called "Revenge of the Jocks" where a famous athlete takes over as editor for that issue. The front cover features the athlete in question tearing up last year's magazine, which features last year's cover athlete tearing up the previous year's magazine, etc. etc.
- Digimon Rumble Arena (a Fighting Game spinoff from Digimon) featured one arena with a copy of the screen displayed as a colored hologram near the top of the arena, and the Droste effect varies in depth according to the camera's current position.
- Although several Mario Kart games have tracks with monitors displaying live race footage as it happens, the size and placement of these monitors around the track generally prevent a Droste effect from developing.
- In Portal, place two portals on opposite walls and look through the resulting "tunnel". It may be the first game to where it is also possible to walk (or fall) through them. note
- The first-person "tunnel" effect in the final levels of Super Star Wars: Return Of The Jedi were rendered using an analogous method, in which as one tile increased in size, another, smaller (and usually identical) tile appeared inside it, and so on. See it here.
- Dwarf Fortress art includes images of "historical events", which includes artifacts, and since the object is created before art is added to it, the content maker sometimes depicts an artifact on itself. Moreover, a glitch/repeatable exploit adding more art and law of large numbers make it happen. The first reported was the statue aptly named "Planepacked", among "an ungodly amount of items built into it" including 73 images of itself. Read here the description of its full glory, as well as of this and another similar exploit.
- The mirror leading to Satan's altar in Tecmo's Deception, although its range is too small to show much more than itself and the surrounding wall.
- There's a manuscript page like this in Alan Wake: "I lifted the page in front of my eyes and read it. In it, I lifted the page in front of my eyes and read it. In it..."
- And, by extension, the entire premise is this. Alan Wake is being forced by a dark supernatural power to write the very same into existence, as the very same dark power can only materialise horrors that creative human minds have written. This way, Alan Wake basically trapped himself and everyone around him in his own work... retroactively.
- In Paper Mario: The Thousand-Year Door, this can happen in the Glitz Pit when the huge monitor set-up at the back of the arena shows a front view of the arena, wherein the huge monitor set-up at the back of the arena shows a front view of the arena, wherein...
- One area of the Alpha Labs in Doom 3 has a security monitor. The player can cycle through a number of cameras, including a camera looking at the screen, so the Marine sees himself seeing himself, etc.

"No pencil is sharp enough to draw as fine as you can think, and no paper large enough to hold your imagination. In fact, it is only in the mind that we can conceive infinity."
- In the I Am Weasel episode "I Are Legend", Weasel realizes that people are watching him on TV, and at one point, we see him standing next to a TV with an image of the scene on the screen, leading to this trope.
- Kaeloo: In "Let's Play Paranormal Stuff", Kaeloo, Stumpy and Mr. Cat, standing right in front of Quack Quack, open a Portal Door to the inside of Quack Quack's head. As a result of them standing in front of Quack Quack, this trope occurs with the door.
- Stand two mirrors opposite each other. Observe.
- "Video feedback" can be triggered by pointing a video camera, or a computer webcam, at any screen which is displaying the camera's own live footage. (Example◊)
- An episode of MythBusters actually had Adam wearing an Infini Tee of himself, possibly as a Call-Back to this image.
- Audio feedback works on the same principle— a microphone recursively amplifying the sound from a speaker— but you get that horrible screeching noise. A better match for the concept of the trope can be had through a delay or echo effect, which replays the same sound with decreasing volume.
- An early transatlantic satellite broadcast included a monitor on the wall behind the presenter which showed the return signal from the satellite. Satellite delay meant that the image on the screen took about half a second to cut from a test pattern to the image of the presenter with a test pattern on the screen behind him, and so on.
- In mathematics, the concept of Self-similarity.
- The concept of recursive functions in programming is pretty much that. If you don't put a stopping condition, it will repeat itself until it runs out of memory. On an unrelated note, modern operating systems guard against the aforementioned programming oversight / malicious code. Before infinite recursion can happen, the program will be terminated by "overflowing out of stack", which is basically exhausting the (fairly small) space to note the connections between the recursing function(s). As for forkbombs, it's one of those things that modern UNIX-based OS actively try to prevent. You can't make too many forks at too short an interval, and in some cases there's a maximum number of forks you can do.
- "The Little Schemer", a Lisp textbook, befittingly has a Droste cover, since what would Lisp be without recursion? note
- During the stage show of Depeche Mode's 2006 "Touring the Angel" tour, which featured a large LED video wall behind the stage, the screen would often feature a medium-zoom view of the performers with the wall directly behind them. A (perhaps unintentional) half-second delay loop resulted in a "stepping" effect, which was enhanced by blinking lights and camera flashes. See here for an example.
- In heraldry this is called "mise en abyme" (from French "placed into abyss"). It was fairly common in medieval Europe. More recent examples include:
- Virtual Machines. You can run a "virtualized" operating system inside that very same operating system, recursively ad infinitum in theory, hardware resources notwithstanding.note This is getting more and more common these days to prevent the headache of having to craft policies for many, many users that share single administrative space. Having an OS emulating the very same OS also cuts down the hassle of having to provide different updates.
- Some remote desktop clients like LogMeIn allow the user to "remotely access" their own computer, which has predictable results. Odd behavior will be present, such as logging out the user when the window is closed, or the mouse not being able to access the window.
- Until a recent update, AirServer (which allows AirPlay mirroring to a Mac) allowed a Mac to mirror to itself. If a Droste image wasn't the result, then garbled colors and glitchy text would take its place.
- VLC has a feature that displays the contents of the desktop. If the VLC player is still on the desktop, this causes a Droste Image.◊
- Wil Wheaton has made an InfiniTee (see above) of himself. He is fond of posing in the position it pictures while wearing it, resulting in a surreal meta-recursion.◊
- At a fan convention Jensen Ackles and Jared Padalecki were sitting on stage in front of a screen showing them on stage resulting in this type of image. Due to the delay when they turned to look each distinctive layer showed them turning one after the other. It can be seen here.
- The village of Godshill on the Ise of Wight contains a beautiful model village; specifically a scale model of Godshill itself. It is so accurate and detailed that it contains a perfect scale model of the model village in Godshill. The model of the model is so accurate and detailed that it contains a perfect scale model of the model of the model village in Godshill...
- In computing, a quine is a program that produces a copy of its own source code and nothing more.
