This video has to be seen to be believed. Some guys strapped LED covered vests on sheep and then had the dogs herd them in specific patterns to create ridiculous art on a hillside in Wales. They even play a game of Pong and recreate the Mona Lisa using different colored LEDs on sheep in a pen. You just have to watch it to understand. Then, I think we'll all agree, sheep: not just for sex anymore.
