Prototype Submitted to Make-a-thon Competition

MAKE magazine's Make-a-thon competition  awards up to $5000 for creative DYI projects submitted to their website. With my friend (a college friend I met at Rice Univ), I introduced LED guided dance floor.
It is an extended version of DDR (Dance Dance Revolution) with higher resolution and size. Take a look!
