Microsoft has an art installation. While I'm sure you've never associated Microsoft with artsy stuff, their latest effort is an interesting departure.
The Cube is a neon kaleidoscope cube (who would have thought?) powered by four of Microsoft's Kinect motion-tracking cameras hooked up to four computers.
Attendees of Seattle's Decibel Festival could stand in front of any side of the cube and see a digital avatar reflected.
Not just their image, because the piece digitally represents every other side of the cube at the same time. That means that four people on different sides of a cube can be joined for a digital dance party.
The idea, I think, is to bring people who may not be dancing in sight of each other to vibe off of their unseen dance team's virtual reflection.
