"Stop hitting the bunny girls!" - That guy in the Slap Stream tutorial.
A spiffy little gamepack/addon to the PlayStationTwo? owned by RichardGarfinkel which includes a camera and some motion-detecting software. Each game involves standing in front of the camera and moving in different ways. For example, Kung Foo has a bunch of little guys running at you, and you have to swat them away by swinging your arms (using juggling pins is cheating!).
DanCicio has the title of the only person awesome enough to beat Kung Foo.
All in all, a lot of fun, but only with an audience.
