Gene Levine creates some of the best stereograms out there. I love his 3D stuff! i highly recommend two books full of his great art: Eye Tricks... and Hidden Treasure 3-D Stereograms, both of which one can get at Amazon.
(You have to get your eyes to diverge slightly and lock into place in order to view these properly, of course.)

Speaking of 3d, we just saw Christmas Carol in 3D with Jim Carrey; i highly recommend it! Awesome!
Let the 2-D-ers rest (flatly) in peace!
Flat kites reek too... of course!
