The funny thing is that, unlike fake UI in other movies, this was indeed a real demo for silicon graphics computers: http://www.sgistuff.net/funstuff/hollywood/jpark.html
Towards the end of the movie the kids use the computer to lock the doors. This is the great moment of fsn (“fusion”) the File System Navigator which is a real demo application and was not written for the movie. A binary was available from the official Silicon Graphics website for a long time.
It was a real 3D filesystem navigator, which may sound like a bad idea, that’s because it was a bad idea.
For the time it came out it looked pretty cool at least, which at least all was needed for the movie. I remember reading up years later how it was an actual program which I thought was pretty neat, they spared no expense in their computer visuals heh. After actually working in enterprise systems I do understand how awful that’d be to work with.
It’s got all the files of the whole park. It shows you everything.
If movies have taught me anything, the internet is green blocks that you have to fly around. Be sure to avoid big flashing red things - those are computer viruses
