Water pipes, ducts and similar things have a tendency to be arranged in ways that resemble great walls of metallic spaghetti.

This is especially common in {{videogames}} that use thick pipes for SpaceFillingPath[==]s, InsurmountableWaistHighFence[==]s, or just generic platforms in an AbsurdlySpaciousSewer or EternalEngine.

Can sometimes be TruthInTelevision due to people taking the easy path out and just using whatever scrap parts they happened to have lying around.

!!Examples:

[[folder: Film ]]

* Parodied in the retro design of Terry Gilliam's ''Film/{{Brazil}}'', which had exposed ductwork everywhere. It even lampshaded the fact by having somebody advertise ducts on TV.
* ''Film/TheThreeStooges''
* An underground area in ''Film/TheGoonies'' has one. Sloth pushes on a pipe and causes a traffic accident above.
* ''CityOfEmber'' has the Pipeworks workers, whose job is to patch up the incredibly intricate network of pipes that brings water to the citizens. Or rather, they patch up the patches over other patches that someone else, a long time ago, put on some more patches.

[[folder: Literature ]]

* The first time Ken sees the Nuclear Utilisation Technology Centre in the ''Literature/{{Temps}}'' story "Leaks" by Creator/DavidLangford, he thinks "Ducts!" and expects to hear the background music from ''Brazil''.

[[/folder]]

[[folder: Live-Action TV ]]

* The opening credits animation of the third series of ''Series/MontyPythonsFlyingCircus''.

[[/folder]]

[[folder: Music ]]

* Music/{{Animusic}}'s "Pipe Dream" and "Pipe Dream 2" videos have, as their names suggest, pipes that run around all of the instruments and around the walls. Some of them even launch balls to strike the instruments like mallets.

[[folder: Tabletop Games ]]

* In ''TabletopGame/MagicTheGathering'', the third sphere of Phyrexia is described as an [[http://www.phyrexia.com/images/continuity/maps/Phyrexia.bmp "impenetrable tangle of metal pipes".]]

[[/folder]]

[[folder: Video Games ]]

* ''VideoGame/PipeMania'' and its imitators - love 'em, love 'em so much. But if you're ScoringPoints, you end up trying to get as many pieces filled as humanly possible, so you end up distinctly avoiding the straight route and trying for as many twists, turns, and go-back-throughs as possible. Bonus if you get a big square of 'em made out of two-ways rimmed by U-turns, so the water goes through the whole square once and then goes through it all one more time just to ensure you've covered enough territory.
* ''VideoGame/SuperMarioBros3'' actually has a world called 'Pipe Land/Maze', which has quite a few levels which most probably come under this (aka, note the vast amount of pipes which don't do anything other than make temporary walls rather than actually taking anything anywhere) Although the background in the remake is even more completely insane in terms of pipe layout. World 7-9 has a particular pipe maze level, though you don't travel through the pipes. A more straight example is World 7-1.
* ''Franchise/SuperMarioBros'':
** World 6-2 of the original ''VideoGame/SuperMarioBros'' also has an inordinate amount of pipes, many of which can be entered, implying that it may be the first attempt by the series. You don't travel through pipes in Mario Bros.
** In World 8-4, you have to go down the pipes to progress through the level and reach Bowser, and going down the wrong pipe will send you back to the beginning of the level.
* World 6-1 of ''VideoGame/SuperMarioBros2''. 21 jars and only one of them has the key that leads to the end.
* ''VideoGame/NewSuperMarioBros'' has levels 3-A and 7-A, and both even mimic the background layout of their [=SMB3=] counterparts, only with updated graphics.
* ''VideoGame/RatchetAndClankUpYourArsenal'' has an (almost entirely optional) AbsurdlySpaciousSewer section that fits this bill precisely. There are 98 "Sewer Crystals" to be found in this maze. It's hell if you're a completionist, as there's a skill point for getting all of them.
* ''VideoGame/SonicTheHedgehog2'' for the Game Gear/Master System, has the oddly named Scrambled Egg zone, which is basically a mass of pipes, and you have to very quickly choose ways to go sometimes. Often, you'll get it wrong and get flung into spikes. Trial and error at it's purest. Used slightly in Sonic Chaos's Electric Egg, and less so still in Triple Trouble's Atomic Destroyer, both with less cheap penalties.
** Oh and Sonic Blast's Blue Marine zone, an icy underwater hell full of strong currents and pipes. You can breathe in the pipes, but that is almost the level's only saving grace. To say it is arduous doesn't even cover it.
* You'll see one of these in ''VideoGame/BaldursGate II'' if you explore the Shadow Thief guildhouse proper. It's apparently used for training purposes.
* In ''VideoGame/{{BioShock|1}}'' you need to complete a Pipe Maze screen to hack vending machines and security systems.
* ''VideoGame/WheresMyWater'', which takes place in a sewer system, has lots of pipes. Some of the levels invoke this trope, there's even a level named "Pipe Maze"!
* [[http://i89.photobucket.com/albums/k213/yuzure/tvtropes/screenshot_2009-02-20-17-03-25.jpg Found]] in ''[[VideoGame/CityOfHeroes City of Villains]]''.
* In ''VideoGame/{{Something}}'', Pipes n' P-Switches is based on the gimmick of retrieving P-Switches to get rid of the coin blocks and Munchers.
* ''VideoGame/TheSeventhGuest'' has a puzzle like this, but based on an artery connected to a heart. And the things to work with are tilting gates between intersections.
--> '''Stauf''': "This plumbing could get you into hot water!"
* Apple's ''VideoGame/{{Through the Looking Glass}}'' came with a bonus game called ''Amazing''. By default, it generated two-dimensional mazes to solve. On higher difficulty settings, they were intricate Pipe Mazes.

[[folder: Web Original ]]

* Wiki/SCPFoundation's [[http://scp-wiki.wikidot.com/scp-015 SCP-015]], a mass of pipes and plumbing work that have taken over an entire warehouse.
* A minigame on CartoonNetwork.com, called Ed Edd n Eddy's Candy Machine, centers on building a huge jawbreaker delivery system in a grid. As you progress, the available parts get wackier, and using more crazy parts gets you higher points at the end of each level. There's a newer, "Deluxe" version with even more crazy parts.

[[folder: Western Animation ]]

* The back areas in ''WesternAnimation/MonstersInc.'' where Randall carries out his evil experiments are practically made of complicated plumbing. They even made custom software for creating the piping.
* One episode of ''WesternAnimation/{{Futurama}}'' had an alien abduction of Fry happen via a needlessly complex tube similar to the famous screen-saver.

[[/folder]]

[[folder: Real Life ]]

* TruthInTelevision: Visit a power plant sometime. The water/steam pipes really are arranged like this because all that stuff has to go somewhere.
** Refineries are basically made of 5 things: Metal beams, bright lights, tight catwalks, huge containers, all lined with and lots and ''lots'' of pipes.

[[folder: Other ]]

* Pictured above, the OpenGL Pipes screensaver introduced in Windows NT 4.0. Windows Vista removed it, but you can still copy the .SCR file from an older version for that retro feel. The more screens you have, the better the effect.
