I don't even know what is Million dollar homepage, but this site is pretty funny. And I think, it would be cool if I buy 1 pixel there.
Here is a link to million dollar homepage if you want to take a look:
http://www.milliondollarhomepage.com/Reason we aren't selling 1 pixel per purchase is that one pixel kinda can't have any cool picture in it and the added link is kinda hard to click (if you aren't zooming like 100x)
