Allright, here’s what I want you to do: cross your eyes so that you see three images. Concentrate then on the middle image to sharpen it a little bit. The middle image should be a composite of both side images. Your brain should interpret that middle image as a 3d-composite image, which should produce this chair in 3D. I had troubles previously “seeing” those stereograms, but finally learned how to look at them. You can expect more interesting stereograms in the future! Previously I posted “Tube of Illusion” but I didn’t manage to visualize it. Try it and comment!
