It would be awesome!
For those who dont know what it is (which is probably evryone), I will explain.
Parkour (Also know as Freerunning or PK) is an extreme sport in which participants climb, run, vault, jump between, over or off things to get from one point to another, sort of like an obstice course in an urban environment. Have a look at this.. http://en.wikipedia.org/wiki/Parkour

I think it would be really cool, as in an LD you could do all kinds of cool jumps, flips, and that kind of thing.
