Nicholas Alexander BuckendorfIn the past I've looked into OS
   experiments that were state-saving machines; and even downloaded
   one in the early 00's - a WIP by a Russian programmer - which
   had no files/folders; programs and data were treated the same;
   infinite UNDO - or time travel to any past point of the
   computer's state instantly - even a spot in the middle of a
   program load; because, there was no program loading. Just
   states. Truly marvelous - I believe it was called Phantom...
   and, alas, last time I looked for it, I couldn't find it again;
   the OS sample I had downloaded sits on a hard drive in a drawer
   that I have yet to get a USB HD reading case for. *sigh* "
