Fsn (file manager)

File System Navigator (fsn; pronounced "fusion") is an experimental application to view a file system in 3D, made by SGI for IRIX systems.
Even though it was never developed to a fully functional file manager, it gained some fame after appearing in the movie "Jurassic Park" in 1993. In a scene in the film, the character Lex Murphy, played by Ariana Richards, finds a computer displaying the interface. She exclaims, "It's a UNIX system! I know this!" and proceeds to restart the building's access control system, locking the control room's doors. After the release of the film, some perceived the visualization as an example of media misrepresentation of computers, citing the computer game-like display as being an unrealistic Hollywood mockup while unaware of the program's legitimate existence.
