The Million Dollar Homepage Scripts

I found a lot of scripts for the million dollar homepages.
They allow to sell advertising space on any website by selling pixels. Pixels are bought in blocks of pixels and then arranged on a clickable image map with the advertiser's link. The good thing, that the script is not limited to just the 'Million Dollar Homepage' type sites. It's easy to find different templates. I'll try to play with them in the future. Did anybody install some of the 'Million Dollar Homepage' scripts? Which is better?
