There are some really neat photos in there. I really liked the Owl one, the Bear, and the Dolphins one. The mountain and foggy one were cool too.
that picture looks like a tree stump which has been chopped off and you can see the layers of the owl.
That owl is just about desktop-worthy. Right now I have that portrait of Kramer from Seinfeld-- not sufficiently moved to replace The Man.
