most people have nailed Blade Runner (1982) on their best-ever list, and, likewise, most know it's based on Philip K. Dick's novel Do Androids Dream of Electric Sheep? here's a new Electric Sheep in the fold: this one is a free, open source screen saver run by thousands of people all over the world and can be installed on any ordinary PC or Mac. When these computers "sleep", the screen saver comes on to allow other computers communicate with one another (via the internet) to share creating abstract animations known as "sheep". The result is a collective "android dream", an homage to Dick's novel. creepy cool.
