4480 - Illusion


Here's a cool illusion...


From the article...

Edges define an object's shape. Without them, we wouldn’t know a square from a circle. But we don’t need a complete mold for a figure to take form. A prime example? The eerily vibrant triangle above.

In reality, no triangle exists. There aren't any connecting lines within the sectioned colors to create it. Yet, our brains trick us into thinking that the Pac-Man-like characters are full circles, topped with a 3D triangle.

The illusion depends on careful placement. Our minds can make do with scant information, says Christof Koch, chief scientist of the Allen Institute for Brain Science. Here, the Pac-Man shapes sit at the would-be triangle's edges, so we reckon a triangle is actually there.
