Mechanical chain reaction Ad
This Honda Accord Ad is just too fun and impressive. A domino-like chain reaction built of a cars mechanical part.
Slashdot has a post on this too, with links to mirrors.
Unrelated, but just too cool: go get the Matrix Reloaded trailer from one of the mirrors listed on this slashdot entry.
Still completely unrelated, a funny cats video compilation (also available here).______________________________________
