Basketball Extreme

I personally love basketball. Just saw this video which is some sort of extreme basketball show, like basketball on steroids with a good shot of ecstacy to boot. There's a sort of spring board which the players use to jump in the air, flip around, pass the ball to each other and score, but hey, trying to explain it really doesn't do it justice. Take a look, it is just unbelievably and ridiculously fun to watch:



That's just amazing. How do you even start practicing something like this?
