I can’t explain this as well as the creators can:
Electric Sheep is a free, open source screen saver run by thousands of people all over the world. It can be installed on any ordinary PC or Mac. When these computers “sleep”, the screen saver comes on and the computers communicate with each other by the internet to share the work of creating morphing abstract animations known as “sheep”. The result is a collective “android dream”, an homage to Philip K. Dick’s novel Do Androids Dream of Electric Sheep.
Anyone watching one of these computers may vote for their favorite animations using the keyboard. The more popular sheep live longer and reproduce according to a genetic algorithm with mutation and cross-over. Hence the flock evolves to please its global audience. You can also design your own sheep and submit them to the gene pool.
I LOVE this idea! I installed it on my PC at my house. It does take a while to download all the “sheep”, but it is well worth it. They recommend leaving your PC on all night after installing it (after one night you should have all the sheep). Also, I haven’t checked, but I think it said that it takes up about 1GB of space, so make room! I just leave it running to add some much needed atmosphere, and when I see something I like a lot I walk over and press the up arrow on my keyboard. This puts in a positive vote for that design. When I hate something I press the down arrow. If I am indifferent then I dont press anything until something comes up the “stirs me”.
Plus it works on the following platforms:
