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.
