Zevs French grafitti artist

Cool video about Zevs, a French grafitti artist:

I especially like his use of the natural elements by using the shadows. It gives something extra to even use something that isn't there all the time. Really cool idea!
I try to use the natural elements too, by letting the colour or shape of the natural ingredient support the sculpture. But, I am jealous about Zevs using shadows, good stuff!
