I notice there are some sets for sale on 3D Commune for the backdrop tool, which I purchased from here. I know that Nerd said he was hoping to make a set up from any images people sent him, so are these posted with his knowledge. I would hate for to purchase and use them, and then find Nerd does not approve.

The greatest part of wisdom is learning to develop  the ineffable genius of extracting the "neither here nor there" out of any situation...."
