It is quite interesting to know that one University Student from UK went on selling single pictute elements on a web page he created(pixels). He created a blank web page on which he asked people to buy ‘Advertising Space’ in the form of pixels. If i remember correctly one pixel was 100$ worth.
He had started this in August 2005 and at the beginning of this week he had achieved his goal of making 1 million US$. Now this is a very cute bit of thinking.
