This marvelous “piece of art” was created by Koukichi Sugihara, one of the top 10 finalists of the Best Visual Illusion of the Year Contest in 2010. Hence, you can even grab some building instructions off of his website, and construct your very own Magnet-like Slopes. You’ll quickly realize how Koukichi achieved this effect, after seeing the video. What is actually happening is that the orientations of the slopes are perceived oppositely, and hence the descending motion is misinterpreted as ascending motion. What is so remarkable about this illusion, is that it is entirely generated by a three-dimensional solid object and physical motion, instead of a two-dimensional picture.
