Even if you have an expansive all-white room to play it in, this is not how you will look while playing Sonic Free Riders on Kinect.
Perhaps it would help if you had a series of green and purple concentric circles beneath your feet like the Kinect event at GamesCom where Crecente tried out the game. Those are easy enough to put together yourself. Then again, you'd probably have to live in a large German warehouse with black floors and green lighting for that to work.
Most of us will end up looking like the Star Wars kid on a bad day. That's why we never appear in Sega trailers. I can live with that.
