Feedtank is a group of digital artists that use technology to create "playful interactive spectacles". The one that really amazed me was there Dance Floor project called Dance Floor Moves.
It's a colorful, projected, interactive floor that can be installed anywhere. When a person moves over the floor, it reacts. So so cool. I want one in the retro discotech I plan on putting in the basement of my house.
