A few months ago I stumbled across a YouTube video that blew my mind. I found out later that is a form of French physical art called parkour. The aim of parkour is to move between two points as efficiently and quickly as possible.
David Belle (born 29 April 1973 in Fécamp, France) is the founder of Parkour and its most famous practitioner. The opening scene from his movie, Distric 13, is amazing.
