This generally gets laughed at by the geek community..

but get this..that was an SGI Crimson machine running IRIX which was indeed a UNIX based system and that 3d Graphical representation of a file system was called FSN, and it was real. SGI of course thought it was great..

“The year following the film’s release, Silicon Graphics released a rebadged, limited edition Crimson R4400/VGXT called the “Jurassic Classic”, which included a special logo and featured SGI co-founder Jim Clark’s signature on the drive door.”

Too funny.
