Black Hole Sun Optical Illusion

Johan Streulens created this interesting effect. He sent me an animation which was too big to post on the site, but never the less this screen-shot still gives you an interesting experience. This is what Johan wrote: “This is an experiment with illusion. I just move the same picture up and down“. If you look at the center of the “black hole“, it will appear to expand and maybe you’ll get impression it’s pulling you in. I sure did! Enjoy this article, and please share with your friends.
