This is the last post on pixel-selling business, unless something totally thrilling comes up, and an incomplete list of pixel-sites :
ThePixelWars.com claims to have spotted the original Million Dollar Home Page and is now following the development of this idea across the web. This piece of code lets you start your own pixel farm. MilPixel.com is a growing directory of the pixel-pimping biz.
Blatant rip-offs, some with a twist:
MillionDollarHelpPage (charity fundraiser)
TheMillionQuarterHomePage (rip-off of a rip-off?)
