Sundial Mosaic

Sundial Mosaic

Patterns and Simulations

The image is created by iterating a map on a torus (the plane modulo a hexagonal lattice), counting the number of times each pixel is visited during the iteration, and coloring by number. (Poster for SIAM Journal on Applied Dynamical Systems.)

Twisted Scroll Ring in Excitable Media

Patterns and Simulations

This image shows simulations of scroll-shaped waves often found in excitable media - such as heart tissue and chemical reactions.
