If you know anything about the worldwide phenomenon that is parkour, you know that it's not easy. It takes an enormous amount of practice and requires the performer to be in peak physical condition. Dominik Sky is one such person. In the video that follows, he has sustained many injuries but the final showreel is nothing short of awesome. He calls this mash-up, "Window jumps"and when you see it, you'll know why.
If he'd also make a complete mash-up of the fails, would he call it... puts on glasses "Windows crashing"?
