Through a glass brightly

Through a Glass Brightly
Ever wonder what those refracted -- or reflected -- patterns of bright light cast by a curved surface (in this case a glass of Peroni at Villa Dolce in Middleton) are called? They're caustics, named after their ability to burn if a light source like the sun is bright enough. They're common in all sorts of natural settings, from rainbows to the ripples of sunlight on the bottom of a swimming pool. They're also important in computer graphics.

Try it large on black.
