Dominoes topple forever, no setup required

It's great fun to watch a domino smackdown, but who wants to deal with the tedium of setting them back up again? Los Angeles artist Karl Lautman solves that problem with his Ouroborus Domino sculpture, giving you a continuously toppling domino tableau that might be fun for a few minutes, but could quickly become obnoxious.

Come on Karl, make a gigantic world-record-sized version of this thing, and you'll be onto something. Oh wait — to break the record, you'll need to create a sculpture with over 4 million dominoes. On the other hand, we'd rather have a continuously filling wine glass.
