It's a "freestyle mini luge"...so like a sled but better! You sit on it (well, duh) and use the black handle in the center to maneuver as you fly down the hill. I had never heard of these things until I received mine in the mail. Apparently people legitimately compete against one another on them. Looks cool! Can't wait to use it!

Here is a video I found of people racing them in the Alps: http://www.youtube.com/watch?v=ymcapeh3RGY
