Earlier quoted context omitted.
I hated this movie the first time I watched it. And the second. The third time I let go of the need for things to be realistic and took it all in as an artistic representation and snap ... I loved it. One could argue that I loved it all along given that I watched it so many times... but there was a distinct moment where I let go and that's when I was able to see just how wonderful this movie really is.
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.
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:
