Seeing is believing?


I saw this optical illusion over on Google+ — if you look at the set up of the room, and the way the lights are positioned, all I can think is that the “shadows” are painted on? Anyway, I’m still trying to figure it out…

There’s a graphic representation along with the video here. And if you view it on YouTube, there’s a description of how it works. It’s still making my mind boggle.
