This is some neat art -- done in chalk on sidewalks to boot! Story and more pics here http://www.snopes.com/photos/arts/sidewalk.asp

Another one. Keep in mind -- the sidewalk is flat!

Man! People with talent just amaze me! Honestly. Wish I had some.

That is really amazing, nice find!

I would be furious if it started raining.

I think the same thing when I'm at the beach/boardwalk and see somebody turn an 8 foot pile of sand into a huge, beach-going Jesus sculpture.
