M K Productions' NES Screensaver does more than just display an NES game's demo mode (and movies recorded with the group's UberNES emulator) on your screen whenever you stop working on your computer; you can actually tile dozens of games across your screen to watch them all play at the same time.

The video above shows 60 games running across two screens (audio is streamed from an "active" movie, which you can change with the arrow keys). What makes the screensaver really great, though, is that you can click any of the running UberNES videos to take over the game. It's a lot like how OnLive lets you jump into in-progress games, but with locally hosted NES titles!:
