Light from a point source is passed through two wavy surfaces, each like the surface of a swimming pool with a few people in it. This focuses the light randomly in a characteristic caustic pattern, here projected by intersection with a plane surface, as on a pool bottom.

Light from a point source is passed through seven wavy surfaces, each like the surface of a swimming pool with a few people in it. This focuses the light randomly in a characteristic caustic pattern, here projected by intersection with a plane surface.

A four dimensional tranparent torus is projected onto two dimensions, showing characteristic caustic structures, caused by viewing tangent to surfaces at some place.

We peer through several interpenetrating, approximately ellipically-shaped, surfaces.

Caustic IV displays folds, cusps, and swallowtails, which are typical caustic structures, here formed by looking through a ruled, transparent colored threedimensional curved sheet.

Caustic Sea and Caustic Sunset are a matched pair, in fact the same original data. Here is reveal the use of a universal form (caustics) as a medium from rendering other familiar forms, such as a dappled sky or a whitecapped sea. The caustics resulted from ray tracing through several successive random refracting surfaces.
