Shirley

This audio screensaver lets your office computers act out scenes from your favorite movies. Imagine walking down the hall of your office and hearing two neighboring computers talking to each other:

Computer A: Surely you can't be serious. Computer B: Of course I'm serious. And don't call me Shirley.

This audio screensaver would probably work in conjunction with a normal visual screensaver, so you'd still have your standard starfield or flying toasters or whatever. But every once in a while your computer will find other similarly configured computers on your network to have a little conversation with.

Computer A: You know why they call it a "Royale with Cheese"? Computer B: Uh... because of the... metric system? Computer A: Hey, check out the big brain on Brad!

Occasionally, everybody would join in:

Computer A: That's a fact, Jack! Computers B-H: That's a fact, Jack!

The user could drop new sound files into a special folder to add their own movie quotes. If you didn't mind computer-generated voices, you could even have it go to the IMDB movie quotes pages and download quotes to use, for an infinite variety of scenes.
