You know those street-performer/artists you find on boardwalks and stuff who will draw a caricature of you for $10? Someone should do that on the web, based on a photograph. And then people could put the picture on their site. A lot of people seem to be uncomfortable putting photos of themselves up, and a caricature would offer a lot more personality than these Trooper things, which are cool but somewhat lacking in variety. There are lots of people who do custom caricatures, of course, but all of them I looked at except this one (which has a missing order form) make the assumption that you want a print, which of course makes it much more expensive.
