Awesome stuff this, if a little unhinged...
I first saw Parkour on Top Gear. James May was racing through Liverpool in a 205 against 2 parkour tracers. It was awesome. The parkour tracers won of course
Then came Casion Royale, with the opening chase scene. Again amazing stuff, unbelievable at times.
I didn't really know what is was called until recently. So when I found out, I opened up video.google.com, did a quick search and found a few gems (and more searching will show you many, many more).
Only then did I actually have a sicko moment. What happens when it goes wrong?
Clickty click. Here's what can happen.
Very impressive when it all hangs together, but my god that must hurt when it doesn't.
