But actually, there was a really cool site I came across like 3-4 years ago where they were drawing scenes on paper and then some smart software would dig through an image database and
seamlessly stitch elements of photographs together to create an artificial photograph of the drawn scene.
The example I recall was a stick figure playing frisbee (crudely drawn oval) with a stick figure dog and I think the background was arbitrarily chosen. You couldn't tell the photo was fake without studying the background a bit. There was a house that had extra windows and it looked silly.
