Mario Kart Is Getting Real… Real Life, That Is

I am quite fond of Mario Kart. I played it way too much as a kid. And I still day dream of wiping out a few cars on the streets with a red shell every now and then. But now it appears that someone else has taken my dream and turned it into a bit of a reality, with real carts, a real track, and everything else you could imagine (not to mention some awesome CG effects). Check out the video, and then check out the behind the scenes to see how they made it.
