Sketch a friend... or yourself!
This is a facebook app / website, that will take your profile picture (or a friends) and make it into a drawing. It works pretty well, the result is better than I anticipated. You have to login to you facebook account to make it work, which makes sense, how else should it be able to get your profile picture and sketch it.
