Just found this animation in my mailbox which was submitted by one of our fans – Brad Snyder. I’m not exactly sure how it functions, but the illusion should be similar with our famous Spinning Girl illusion. Apparently the gem we see below is rotating in only one direction. Because it is shallow, it gives you impression it changes direction every few seconds. Don’t take me for granted, though. I have a feeling I don’t get this illusion in its full sense. I would appreciate if some of you managed to understand it, and post a clue for me and others via comments section. If my intuition is right, this can easily be one of the greatest illusions on this site. If I was wrong, don’t hate me…
