Shadow Physics Vs Tokyo Squeakers

This must be the most surreal games presentation ever. Not only is the game pretty far out - it's Steve Swink and Scott Anderson's Shadow Physics in more detail than we've ever seen before - but the Tokyo audience is armed to a man with some kind of squeaky rattle thing. When anything interesting happens they all shake their rattles, causing a noise like a hundred laughing insects. Anyway, if you can get past that bizarreness, there's some views of the light-source cleverness in the game and... well it's too early in the morning to explain it properly. "Change your light source and you change your world..." Go take a look.
