Parkour is a really cool technique which takes years of practice, hard work, determination and most importantly power of will and fearless mind to master it.
Serene Teh is an amazing illustrator, one of a kind in this work, he has made a flipbook which illustrates a guy doing parkour out in the streets. He spent several hours in creating this master piece. Your mind would spin after taking a look at this complex design. Kudos to the designer!
