->''"I can see FOREVER!"''
-->-- '''[[MemeticMutation Various people, upon seeing a droste image]]'''

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. In the example from the movie ''Escape From the Planet of The Apes'' below, they referred to it as "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]]Actually, the [[DarkShadows Barnabas Collins]] parody is holding his hand in front of where the third repetition of the cover would be, but that's just nitpicking.[[/note]]

A similar effect can be set up in a HallOfMirrors by putting two mirrors facing each other.

See also NestedStories and DreamWithinADream, which has the layering but not the self-similarity. Also see RecursiveReality which is this trope on a cosmic level.

[[folder: Advertising ]]

* The TropeNamer is Droste cocoa powder, made by a Dutch food company that was famous for using this trope in their ads. See the [[http://en.wikipedia.org/wiki/Droste_effect Wikipedia article]].
* Seen on several cereal packages. You know, the type that feature a picture of somebody having breakfast. Said breakfast of course centers on the cereal, with a package proudly displayed. On that package, we see somebody having said cereals for breakfast. And so on...
* [[http://i142.photobucket.com/albums/r104/CarlotaCores/Doces-1.jpg Royal Baking Powder.]]
* [[http://upload.wikimedia.org/wikipedia/en/e/e9/Land_O%27Lakes_logo.png Land O'Lakes Butter.]]
* Nippon Paint [[https://lh6.googleusercontent.com/-khyf9NYTiIM/Tz3hYNJp4vI/AAAAAAAABIM/XtH62z1cpTc/s1280/2012Stratocaster062.jpg used to have this]] on cans of [[http://www.tradeduck.com/uploads/24489_12932431.jpg Pylox spray paint]], where what appears to be a hand belonging to a woman is holding a can of Pylox, whose can shows the same thing over and over. Newer cans did away with this, although a vector drawing of a hand holding the paint can be seen.
* [[http://i533.photobucket.com/albums/ee340/Acidonia150/tumblr_mbl8s9ikMA1qd4q8ao1_500.jpg This cover]] of the German magazine "Amiga Joker".
* [[http://en.wikipedia.org/wiki/The_Laughing_Cow La Vache qui rit]]. French cartoonist Gotlib parodied this for his series of exhibitionism gags: the cow opens her cloak to show a cow which opens her cloak etc.
* Science mag "Nature" (issue #7476) illustrates an article about science replication with a Droste image.

[[/folder]]

[[folder: Anime ]]

* ''UruseiYatsura 2: Beautiful Dreamer'' had a scene where Ataru is in a room in the school building, looks through the doorway, and sees on the other side of the door the same room that he's in, complete with himself and the doorway, and past that doorway is the same room again, etc. (It seems that space itself is forming loops; earlier there was a scene where we see Mendo run up the stairs past the "camera", only to reappear coming up the same stair and go past the camera again.)

[[/folder]]

[[folder: Art ]]

* Creator/MCEscher's [[http://www.mcescher.com/Gallery/recogn-bmp/LW410.jpg "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.

[[folder: Comics ]]

* In comics, it's called an [[http://comics.org/coverview.lasso?id=42041&zoom=4 infinity]] [[http://comics.org/coverview.lasso?id=66581&zoom=4 cover]].
* An issue of ''Comicbook/{{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. The result is himself, watching himself watching himself, watching himself watching himself watching himself, watching himself watching himself watching...
* The cover of the ''Comicbook/DoomPatrol'' comic "[[http://www.amazon.com/gp/product/images/1401203426/ref=dp_image_text_0?ie=UTF8&n=283155&s=books The Painting that ate Paris]]" also has such a shot.
* Used in TheBeano back in 1954 [[http://i780.photobucket.com/albums/yy82/irmantas67/Beano1954011.jpg]].
* The cover of the one-shot ''[[Comicbook/ElfQuest Elfquest]]'' anthology "Bedtime Stories" is like this.

* French cartoonist Gotlib had one in his "Exhibitionist" gags, with a cow opening her cloak to show a cow opening her cloak etc. The cow is "La Vache qui rite" and ''most'' probably he got the inspiration from her Droste-style ad.
* [[http://vi.sualize.us/_humor_funny_pregnant_matrioska_illustration_picture_gG4J.html Pregnant Matroschka doll gets ultrasound.]]
* Subverted with [[http://img208.imageshack.us/img208/694/athineos016zq.jpg this]] old Creator/CharlesAddams cartoon.

[[/folder]]

[[folder: Film ]]

* This effect is captured in ''Film/CitizenKane'' when Kane passes between two mirrors.
* Creator/OrsonWelles, the director of ''Citizen Kane'', did this again in ''Film/TheLadyFromShanghai'' in a HallOfMirrors sequence.
* In ''Film/{{Spaceballs}}'', the titular bad guys [[MediumAwareness watch the Spaceballs video tape]] to find out where the heroes are. HilarityEnsues when they get to the exact point in the tape that they are watching, although the Droste effect is too small to see much of.
* Happens in ''Film/TheMatrixReloaded'' 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 [[http://chasenchamberlain.files.wordpress.com/2010/01/memento.jpg box art]] for ''Film/{{Memento}}.''
* ''Film/{{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. ''Film/AirplaneIITheSequel'' then cranks this UpToEleven by posing [=McCroskey=] in front of a framed photo of himself posing in front of the framed photograph of himself.
* ''Escape From The PlanetOfTheApes'' uses this as a metaphor for TimeTravel: A painting that contains an infinite regress of images including the painter himself.
* In ''Film/HotFuzz'', the shot of Simon Skinner's smiling face in front of a photo of himself smiling.
* In ''Film/TheHobbit'', after Gandalf is beaten by the Necromancer [[spoiler: a.k.a. Sauron]], the Necromancer appears as the [[spoiler: Eye of Sauron with his humanoid shape forming the pupil, repeating itself infinitely from within]].
* At the end of ''Film/AllAboutEve'', when Eve has supplanted Margot and has a LoonyFan[=/=]StalkerWithACrush 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 [[HereWeGoAgain the cycle is endless and there are infinite Eves out there]].
* Dep. Chief Hardy in ''Film/TwentyTwoJumpStreet'' 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.

[[/folder]]

[[folder: Literature ]]

* "Jack's Story" from ''Literature/TheStinkyCheeseMan'' could be considered a print version of this, as it features an infinite regression of the same story [[NestedStory nested]] inside itself. [[JustifiedTrope Justified]] in that he's (Jack, that is,) telling this story to a ''[[ScheherezadeGambit 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. [[BrickJoke On a later page,]] we see Jack making a break for it.
* In ''TheMouseAndHisChild'', much is made of a particular dog food label depicting a DrosteImage 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 [[ArcWords "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 RamonaQuimby book ''Ramona Forever'' gets its title from a scene where Ramona does this with the angled mirrors in a dressing room.
* In ''[[Literature/{{Discworld}} The Art of Discworld]]'', Paul Kidby's drawing of Dr Whiteface shows him holding a scepter tipped with a whiteface clown that's holding a scepter, and so on and so on.
* The PeterDavid ''Franchise/StarTrek'' novel ''Literature/{{IQ}}'' featured Picard, Q, and Data moving through a HallOfMirrors. 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 ''[[Literature/{{ASongOfIceAndFire}} 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."
* ''[[Creator/UmbertoEco The Mysterious Flame of Queen Loana]]'' has a rare conversed example - probably based on a real Italian soda brand.

[[/folder]]

[[folder: Live Action TV ]]

* The first episode of ''Series/TheITCrowd'' opens with one of these: A shot of [[PointyHairedBoss Mr. Reynholm]] at his desk, with an identical scene on a picture hung on the wall. The camera then [[TheReveal 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.
* ''Series/SquareOneTV'' did something similar to teach viewers the concept of infinity.
* During Steve Martin's "I'm Me" song on ''SaturdayNightLive'', he notices a monitor showing live footage of him, thus creating this effect. "It's me, watching me, watching me!"
* In ''Series/KamenRiderDecade'', Decade's TransformationSequence into his [[SuperMode 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 [[http://www.youtube.com/watch?v=iJjxr3-b7_4 repeatedly zooms in on Decade's forehead of infinity]] until he's suited up.
* An episode of ''Series/HappyEndings'' had Jane doing a slide presentation of her father's interests, one of which was "old-timey slide projectors." The accompanying visual was [[http://oijio.tumblr.com/post/37965323891/and-old-time-y-slide-projectors somewhat unsettling]]...
* In the end of an episode of ''RutlandWeekendTelevision'', [[http://www.youtube.com/watch?v=lbK4N445WBk 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. HilarityEnsues.
** One episode also uses a "Bohemian Rhapsody" style video feedback effect (see below) during a "performance" by an up-and-coming singer whose gimmick is... he's dead. This is a spoof of the effect's popularity (and overuse) on shows like ''TopOfThePops'' and ''TheOldGreyWhistleTest''.
* Stephen Colbert's portrait on ''Series/TheColbertReport'' is slowly becoming one of these, as every season he has a new portrait painted... where he's posing in front of the previous portrait. That said, what he's holding, generally his latest book, is different.
* In an episode of ''Series/MadMen'', Sally and Glen (kids) have a SeinfeldianConversation 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 [[http://en.wikipedia.org/wiki/MTV%27s_Most_Wanted 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 DrosteImage 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.
* ''Series/ModernFamily'' does this to go from the ColdOpen to the opening credits.
* An old Creator/{{CBS}} logo, seen for instance at the end of ''Series/TheTwilightZone'', features a push-in on a CBS eye inside a larger CBS eye.
* An unintentional example happens every now and then on ''Series/PardonTheInterruption'' when the hosts ask Tony Reali if 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 ''Series/DoctorWho'' [[https://www.youtube.com/watch?v=XZ1kRxgKft4 title sequences]] were created using this effect. The original (Hartnell to early Pertwee) sequences were made by pointing a camera at its own monitor and then passing objects across the lens to create the weird "howl-around" feedback effects.
* Abby from ''Series/{{NCIS}}'' gets to enjoy one courtesy of her spy glasses and a monitor showing her the video feed. "Whoa...trippy..."

* TheNewPornographers use TV monitors to create this effect in their [[http://www.youtube.com/watch?v=XBAUQaj6EJo video]] for "Letter From An Occupant."
* The cover of Music/PinkFloyd'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 - TheSmurfs''.
* The album cover for ''Amber Gambler'' by Gorky's Zygotic Mynci.
* The album cover for ''Swing to the Right'' by Utopia.

* 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.

[[folder: Video Games ]]

* ''Digimon Rumble Arena'' (a FightingGame spinoff from Franchise/{{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 ''MarioKart'' 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 ''VideoGame/{{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.
* The first-person "tunnel" effect in the final levels of ''SuperStarWars: 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. [[http://www.youtube.com/watch?v=VuH4HZn52FM See it here.]]
* ''Videogame/DwarfFortress'' 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 [[GoodBadBugs 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. [[http://df.magmawiki.com/index.php/Planepacked 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 VideoGame/{{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 ''VideoGame/AlanWake'': [[http://www.youtube.com/watch?v=OT1NBrcD64I "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..."]]

[[folder: Western Animation ]]

* Used in ''WesternAnimation/TheVentureBrothers'' when #21 and Dean are caught spying on the Murderous Moppets.
* The ''WesternAnimation/DarkwingDuck'' episode "A Brush With Oblivion" had one of these as Honker Muddlefoot's art project.
* In the ''WesternAnimation/JusticeLeague'' episode "Wildcards", one shot has the Joker showing his [[DoNotAdjustYourSet successful takeover of TV channels]] by appearing at a TV screen, which shows him on television in the same shot, and so on.
* An old Creator/RankinBass cartoon called ''Tomfoolery'' had a gag involving [[http://www.youtube.com/watch?v=Wo0DjdCn6pk an animated man holding a Droste image of himself]] that zoomed in for several seconds. After a while, the narrator quipped, "This could go on all day!"
* One episode of ''WesternAnimation/PhineasAndFerb'' had Doofenschmirtz explaining how he was able to capture Perry the Platypus again through a series of pictures on canvas that ends up reaching his own explanation thereof. The final picture is of himself pointing to a picture of himself that goes on for several times (but ''not'' getting smaller) until the canvas runs out of room.
** In "Meapless in Seattle", Ferb unearths an old urn with a picture of an ancient Greek version of himself holding an urn with a picture of an ancient Greek version of himself holding an urn... and so on.
* [[WesternAnimation/LooneyTunes "Drip-Along Daffy"]], a Daffy Duck cartoon set in TheWildWest, plays with this by showing a WantedPoster for Nasty Canasta. When the picture seems to move, we discover it was Canasta himself, standing in front of the poster in the exact same pose.
* In ''WesternAnimation/TheSmurfs'' episode "Now You Smurf 'Em, Now You Don't", Vanity presents Greedy with a painting of himself in the exact same pose holding a painting of himself.
* In the ''WesternAnimation/{{SpongeBob SquarePants}}'' episode "No Free Rides", inside of Mrs. Puff's house there is a picture on her wall that shows the exact same shot of Mrs. Puff standing by the door, picture and all.
* In an episode of ''WesternAnimation/SpaceGhostCoastToCoast'', when Moltar is attempting to fix the monitor, it begins showing Space Ghost looking at it as it's showing him.
--> '''Space Ghost:''' Hey look! It's me watching me watching me watching me!
* In the ''WesternAnimation/WanderOverYonder'' episode "The Box", Wander peeks inside the titular box and sees... himself peeking inside the box. The camera then zooms through the infinite progression of boxes and into a DreamSequence.
* Used during Xergiok's musical sequence in the ''WesternAnimation/AdventureTime'' episode "The Great Birdman".
* During ''WesternAnimation/TheAmazingWorldOfGumball'' episode "The Phone" Darwin looks at one on the eponymous phone of him coming out of an envelope then opening his mouth to reveal another envelope with another Darwin.

* 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. ([[http://en.wikipedia.org/wiki/File:Adam_Savage_HOPE.jpg Example]])
** An episode of ''Series/{{Mythbusters}}'' actually had Adam wearing an Infini Tee of himself, possibly as a [[CallBack call back to this image]].
* 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 [[http://en.wikipedia.org/wiki/Self-similar 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 [[ObviousRulePatch actively try to prevent]]. You can't make too many forks at too short an interval, and in some cases there's [[{{Cap}} a maximum number of forks you can do]].
* 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 [[https://www.youtube.com/watch?v=_Ht-4cpMlW4 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:
** [[http://en.wikipedia.org/wiki/Coat_of_arms_of_Russia Present-day coat of arms of Russia]], as illustrated [[http://www.youtube.com/watch?v=e1FsQf_x04Q here]]. The eagle holds a scepter tipped with an eagle, that holds a scepter tipped with an eagle...
* Virtual Machines. You can run a "virtualized" operating system inside that very same operating system, recursively ad infinitum in theory, hardware resources notwithstanding.[[note]]And some virtual machines prohibit virtualizing themselves.[[/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.
** This process of "sandboxing" isn't very common though, as virtual machines are generally used to run a different operating system than the current one.
* 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.
* WilWheaton has made an [=InfiniTee=] (see above) of himself. He is fond of posing in the position it pictures while wearing it, resulting in a [[http://www.cotygonzales.com/wp-content/uploads/2011/08/wil-wheaton-shirt.jpeg surreal meta-recursion]].
