Nice blast from the past! I remember this one. I believe the founder tried to create a follow-up called Pixelotto. By the time it was released, the novelty of the Million Dollar Homepage may have run its course.

Also so much poker and online casino ads! I was almost disappointed that there wasn't porn.
