Swimming Fish optical illusion was originally created by Emily Knight and Arthur Shapiro. It was a 2007 Finalist in the Best Illusion of the Year Contest hosted by the Vision Sciences Society. However, there is a guy called Excel Hero, who recreates optical illusion using nothing but Excel. As he explains, the fish appear to wiggle up and down, but this is again just an illusion – all of the little bastards are actually standing still!
