  Caustics are the optical effects that occur when light gets bent several times by some refractive material. You can observe them for example on the bottom of a swimming pool or when light shines through a glass bottle. I find the resulting shapes very attractive so I have tried to create a tool which allows me to create and explore caustics or rather pseudo-caustics.
