это не моя картинка, это ссылка на милый проект электрическая овца.
When the screen-saver is activated, the screen goes black and an animated 'sheep' appears. Behind the scenes, the screen-saver contacts a server and joins the parallel computation of new sheep. Every fifteen minutes 24/7 a new sheep is born and distributed to all clients for display. Each sheep is an animated fractal flame.
интересно, что у них стоит sheepserver.
