feature suggestion: non-interactive screensavers "games" picked randomly and played when machine is idle

ability to create a (game???) that's non-interactive and runs as a screensaver when the machine is idle (to......... minimize screen burn in! yeah!) :-) haha

every time the machine is idle, it'd pick a different screensaver

would screensaver .............. also be bundled/distributed/cached.........????? overkill.........??? but it'd be nice yes.
