From Wikipedia :
(Le) Parkour (English: the art of movement) is a physical art of French origin, the aim of which is to move from point A to point B as efficiently and quickly as possible, using principally the abilities of the human body. It is meant to help one overcome obstacles, which can be anything in the surrounding environment � from branches and rocks to rails and concrete walls � so parkour can be practiced in both rural and urban areas.
First off a Latvian group Dvinsk Clan showing off their skills.
Next in line is the talented parkour artist, stuntsman and martial artist Cyril Raffaelli. And finally the founder of the art – David Belle himself.
I wish I was that skilled.
