There are some niche 3D file system browsers/shells out there, but none as captivating as what's shown in the movie (or the linked "animated experience") that I can find.
Not quite filesystem navigation, but SGI IRIX's Performance CoPilot software had an IrixGL (OpenGL's precursor) UI for monitoring things like memory state, CPU/storage loads, etc.
The PCP is absolutely nowhere _near_ the graphical wizardry of the state of this app, and the overlay of executing code atop a given directory structure is quite beautiful (practicality be damned), but I can see the inspiration.
I do wonder if, on a modern Linux system with SELinix, this model (code accessing a directory) is actually closer to viable? SELinux's contexts/labels for subjects overlaying with the same for objects can, I imagine, be visualized. The normal access patterns would be way too overwhelming, I think - but exceptions/policy violations? :ponder:
PCP is still in active development. It's very cool, but probably made obsolete by otel and others. I used it on servers and services regularly until a few years ago. Very lightweight, robust and powerful.
