This was done by Peter Donnelley, obviously in the sand. I thought this was a very interesting medium. There are suprisingly a number of sand artist out there. I chose this one because it was not a sculpture type piece which most of the other ones are. I really like the shape of this whole piece, and how it seems to just come out of no where. I also think the squares are awesome. I would not even know where to begin if I had to do something like this.
