Mike Hurnaus may have saw “Honey, I shrunk the kids!” when he thought this idea up. Mike built a what may be the world's largest Windows Media Center remote control.
How Mike created the pad is rather smart, he ordered some Dance Dance revolution mats and used an adapter to hook them into his computer. He then used a modified version of a DirectInput example by Mark Harris to create the library to interact with Windows Media Center. Mike even has the source code for his WMC/DDR project available for download too!
Looking at this controller, I think Mike finally found a way to work out and channel surf at the same time!
