Lightspace Corporation : Cutting Edge Interactive Lighting Surfaces: These people make lighted floors that sense weight (I’m guessing), and light up with different effects based on where someone is standing.
Using the latest LED and pressure sensing technologies, Lightspace has created the ultimate club experience by offering an interactive dance floor that not only engages but responds to club goers movements on the floor.
Watch the video (in the green box on the home page) to see some little kids playing one of the floors. It’s pretty snazzy. I want one for the wall of my office, so when I get frustrated and punch it, I’d feel like The Hulk.
