Well, Sketchee is probably the simplest app imaginable. You can build out on top if it. For instance, a canv.as derivative app, where you could prepopulate most popular meme images and let people create and share photobombs with their friends.

Also, basic things like location & media sharing were intentionally left out for third party app developers to get creative with.
