I ran across this today and tried it - so worth it.

It’s a screen-saver that does mutating, “genetic” computer-generated animated art for your screen-saver, and distributes these across the internet to everyone else who has the screen-saver installed, and users can vote for or against the various “electric sheep” (up arrow key votes yes, down votes no) so that cooler ones get promoted.  I took the following image from the sites gallery of current images (which fluctuates - they render new “sheep” images from user’s machines during idle time/bandwidth) and scaled it up - it’s a desktop now.

This is a link to the image because the thumbnail isn’t working for some reason.

I love that MATRIX screen-saver I found and will probably go back to it from time to time.  Meanwhile, this.
