Animations

In my spare time I like to make hypnotic cyclic animations with trigonometic functions. On this page you'll find a grab-bag of some of the fun ones I've thrown together over the years, all made in the extremely useful and lightweight freeware program "graph", which I strongly recommend to anyone who will listen.

Rotor

A demonstration of how polar functions can produce interesting patterns if you feed them trigonometric functions

Spring Projection

A demonstration of how 2D geometry can give the illusion of a 3D object

Mean Median Mode

A demonstration of mean, modal and median stats on a 1D assymetric PDF

Spiral Anim 3

A fun spiralling animation

Flower

A polygon with vertices tracing out paths on a shifting landscape

Basket Weave

A fun demonstration of Lissajous Curves at changing frequency

Binary

The first 3 modes of a square wave with counter-rotating phases wrapped around the polar axis

Dotto

Point clouds distributed according to Gaussian (red) and Cauchy (Blue) distributions, condensed onto the unit domain
