When you think of 3D chalk art, Julian Beever is probably one of the artists that come to mind, but Kurt Wenner is also one of the greats. Born in Michigan, Kurt worked for NASA briefly as an illustrator, before moving to Italy for art study. The Gears of War mural above was created for E3 2006. Click here for more pics.
