Stare at this moving spiral optical illusion for about 30 seconds, then look at your hand, or a pen. You’ll see it start to move and distort whatever object you look at. This is another one of our favorite optical illusions! In fact it’s so great, that it took me a long time to actually publish this article about this spiral illusion because I’ve been staring into the spiral and am totally mesmorized! See if you can break away after you watch this picture and check out some of our other spiral illusions!
