We are pretty good at judging the shapes and sizes of things—most of the time. This example demonstrates a slight chink in the system. The Banana and the Chili Pepper shapes are perfectly matched. Drag one over the other to prove it. Turn the Grid on if it helps. Now place the two shapes side-by-side with the Grid off. Compare them. Switch them around. Compare them again. Do both shapes look bigger when they happen to be on the left-side? The secret is in the shape. We can't help comparing the long curve of one shape against the short curve of the other. Our brains leap to a conclusion: that the long-curved shape must be slightly bigger in comparison. Art: R. Ausbourne |
