I'm not sure I've ever seen anything quite like these 3-D illusion projections on buildings. I wasn't completely sure it was real until I looked closely at the edges of the second building's columns. The projection doesn't extend an inch beyond them. I wonder if it looks that interesting from off-angle views?

Update: It seems that video is a demo, and like most demos it over-promises a bit. Still, the actual item is quite interesting.
