http://www.ubernes.com/nesscreensaver.html I am sure some of you have seen this, but I just stumbled upon it today after watching some SSF4 tournament (random, I know). It is a NES emulator screensaver that shows an array of different games running at once. The cool thing as they are playing, you can actually enter any game and take control of it right where it was on the automated game play. Kind of hard to word, but its like watching a video of someone playing and being able to take control at anytime. I absolutely love this idea & see it staying as my screensaver indefinitely. Just to note, it is an actual emulator that requires roms to play (& watch I would assume, as I think the playback files themselves are just key inputs).
