Finalist
Capricious Hearts
Kokichi Sugihara
The object appears to be four hearts in a line when we see it directly, but the reflection in a vertical mirror behind the object appears to be the set of all four suits of the trump, i.e., diamond, club, heart and spade. We know that the shape of an object and its mirror image are mirror symmetric to each other, and hence heart cannot change to diamond, etc., in a mirror; the behavior of this object seems impossible. However, this is possible because our perception is subject to optical illusion.
