These guys are UNBELIEVABLE. Blessed with an amazing affinity for drawing, Julian Beever and Kurt Wenner create pieces of trompe l'oeil, illusions of a 3-D nature, on the sidewalk simply with colored chalk.

Even when you get to the end of the scroll, you'll find yourself going back through them over and over! Your first inclination will be to think it's a scam and that the pictures are real photos. Fortunately, they provide camera shots from different angles so you can see that the chalk art is flat.

According to my kids, this is a popular site for their friends who become inspired to get back to school and dig in to the chalk bucket to create their own masterpieces.
