Be Funky (www.befunky.com) allows you to upload photos into their system that can be altered into cartoons, charcoal drawings, and a dozen or so other styles, each available in many shades/colorings. A fun way to jazz up a photo. For best results, make sure the photo is fairly close up and with little clutter in the background.
