Pretty mindblowing technology to allow a user to hand sketch a scene, and the system almost-automatically creates the scene from an internet image search. It seems kinda simple unless you've ever tried to composite several images together and had to deal with lighting color, texture, and the raft of other things that tend to go completely wrong.

It's only a matter of time before all the user interaction is gone in selecting appropriate images and the system can automatically create dirty pictures of me and Megan Fox (stolen joke from Reddit).
