Very nice! There was an artist (or plural - artists, IIRC it was a couple) who made 3d posters using real life objects and photography. They placed them in various configurations, hanged them on invisible ropes, and took photos of them, it also included light and shadow play.
If anyone knows the name of the artist(s), I would be super grateful. I've been trying to google them for a very long time with no luck so far. :)
