Chalk Art

I am so in love with this sidewalk chalk art! It really amazes me and I wanted to share! It has been popular of years and there are quite a few prominent artist, but I really love Julian Beever and Kurt Wenner who use a style called trompe l'oeil ( French for 'deceive the eye', it is an art technique involving extremely realistic imagery in order to create the optical illusion that the depicted objects appear in three dimensions.)
Look at some of this art work!:
