    Once both figures are seen, I can change perspective at will. Does anyone know what is happening when I do this? Is this simply a matter of recalling a different memory?

    Every time I see some picture/movie/animation on the net that says "look for n seconds at something" I know what's coming to me :wink:

    Here's a couple more.

    Renderings I did based on Escher's work. (the trick here is that these are 3-D models, not 2-D).

    I think so too. But I don't know why I couldn't count how many black spots are there in Optical Illusion 1.

    These 2 pictures are very famous
