Million dollar idea: I sure wish I had thought of this simple-but-brilliant idea. A young UK college student posted a webpage called MillionDollarHomepage, which started off with a million blank pixels. Anyone who wanted to purchase ad space could do so for $1 per pixel. The home page is guaranteed to stay up for a minimum of 5 years.

As of today, he's sold 999,000 of the pixels. In fact, the last 1000 pixels are being auctioned on eBay and the current price is over $150,000(!)

It goes to show that there's no shortage of great capitalist ideas...
