Our pal Philipp Lenssen of Blogoscoped and Mike Dougherty came up with a pretty nifty iPhone app called The Magic Artist. All you have to do is take a snapshot (or open an existing photo) and watch it turned into a painting brush stroke by brush stroke:
This project started its life as a JavaScript/ Canvas prototype (I was looking into letting you enter a term, grab an image via Google Images, then draw it), but I was running into a zone where it looked like I would have had to support image uploads or provide some image proxy for the necessary JavaScript rights. The iPhone app, programmed by Mike Dougherty, solves this issue, and the nice thing is that you already have a camera at hand when you have a phone (and that Objective-C as used on the iPhone is fast).
