Dual Photography

It’s easy to see how a mirror allows you see around the corner by reflecting light, but can you exploit the reflective qualities of any surface to do the same?

I hope we all thought of Blade Runner when we saw this. In this case they still need to be able to control the light source, but I can see how this could one day lead to what my intro blurb suggests, that everything is a mirror, and from any image you have another layer of data, the reflection data from which you can reconstruct unseen things.
