The winners of the 2018 Best Illusion of the Year contest have been announced. Once again, mathematician Kokichi Sugihara of Meiji University has taken the top honor, with his illusion called Triply Ambiguous Object. It's just a flat picture, with a 3D object drawn on it. But that object looks different in the two mirrors placed near it. You think you know what the object looks like, but when it is rotated, it looks ...different. Trying to suss out the individual shapes in the mirror images will tire you. So take a look at the second place illusion, from David Phillips, Priscilla Heard, and Christopher Tyler. It's called Movement Illusion with a Twist.
