There's an exhibit in Langkawi that is all about this 3-D art. When I was walking through it I didn't notice anything special. But I was recording with my GoPro, and in going over the video I noticed that the images were strikingly 3-D. So I think these things are great for a single-pupil/lens observer, but having two eyes makes the effect less spectacular. In other words, they photograph well but aren't that dramatic IRL.
