When I was a boy, Legos were good for having crash-em-up derbies (Instructions: You and your friends take a big green board each and build cars. The owner of the Legos gets all the good wheels. Crash the cars into each other. Repeat.) Now they have the damn things solving Rubik’s Cubes like some sort of manic hog-skinning machine that needed some time off. The full instructions and code are here but I enjoy just watching this thing go.
