Free Running is the 'flips and stuff'
Parkour is what andyson is doing. Wallspins, Wallruns, Vaults, Precision jumps, etc.
4 guys from Worldwide Jam, the biggest Free running team in Britain [the ones who appeared on Britain's got talent] came up to where I live and had a jam session. It was fun. I'd love to talk more but I'm invading. Sorry =O
