What a little chalk will do

I stumbled over this pavement artist's site the other day:

Julian Beever

I wish they would show more of the pieces from the "wrong" angle. It's bizarre how distorted he has to make the images to create a 3-D look from one direction. Some of them, it's hard to believe are chalk.

I remember an artist in Royal Oak AGES ago... probably 1994 or so, who was doing impromptu 3 minute paintings of space using spray paint in really unconventional ways. They were beautiful, and I was fascinated because the process was so simple and foolproof. I tried it later, and came of with almost as nice an image. I'll try to remember how it was done, and make one. If it works, I'll take a picture and post it.
