'Wraparound' Poster

I wonder if we could see a poster which can wrap around blocks, so that we can create designs on columns, corners, odd angles etc, rather than everything being flat. Obviously you can simply draw a picture of something, and make it look like it has depth, but with columns and the like, i think it would be a useful thing to have.

I'm just not sure if it's even possible. The devs are probably reading this going,'pfft! dream on junior!' Hee hee.
