When considering communication events for a winning prize I thought of a fireworks display. The physics for particle movement in three dimensional space are beyond […]

This is used to create wonderful images of mathematical fractal functions. Fractals are functions such that whenever you look deeper into a section of the curve you see repetitions and self-similarities to […]
