When it comes to creating motion illusions, Akiyoshi Kitaoka is in a league of his own. In one of his latest examples below, titled Beating Heart, the pink and red heart appears to move on top of a green background. If you slowly scroll the page up and down while looking at the image, it almost seems like the heart is actually beating.
