I think this is the nicest one of these I've seen—seems to actually work in a non-superficial way, from the package manager, shell, system settings, chat app, "p3" ("pseudo peer-to-peer"), system backup (downloads filesystem contents as zip), to running Half-life Uplink or Doom. Seems like if you were a deeply unusual person you could actually do some computing in here :) main thing missing is a browser.
