The Colourful Geometry of Nature

This website promotes recent research concerning the mathematics of natural imagery, art, and biology. The goal is to combine ideas from chaotic dynamics, iterated function systems and image science to provide a new geometry of form and colour. Topics include colour stealing, fractal transformations, orbital pictures, the chaos game, superfractals, laminations, textures, area-preserving maps and more. Have fun!
