Christian Bechinie's LEGO Rube Goldberg machine uses dominoes, tiny basketballs and some slides to do that same "everything but nothing" thing that all Rube Goldberg machines seem to manage.

I get a little disappointed in the headline that this isn't something I can buy, but that might change: the project is up on LEGO's Ideas service (via Brothers Brick), meaning that if it gets enough votes the company can elect to make a few up and sell them.
