Circular shaped mirrors which are arranged in a grid-like manner reflect a light ray according to the reflection law of geometric optics. While random positions of the light source produce chaotic reflection patterns, it is possible to position the light source so that beautiful symmetric reflection patterns are created.

The application allows you to interactively change parameters like light source position, circle radius and rotation angle of the lattice. Through a simple menu it is possible to select and explore a wide range of symmetric reflection patterns.

A main feature of the simple circle lattice model is that all reflection patterns depend sensibly on the given parameters meaning that the slightest change has a dramatic impact. Long numbers are therefore needed to reveal the intrinsic beauty of the model (see FroZenLight gallery).
