![The smooth motion of rotating circles can be used to build up any repeating curve even one as angular as a digital square wave. Each circle spins at a multiple of a fundamental frequency, and a method called Fourier analysis shows how to pick the radiuses of the circles to make the picture work. Decomposing signals like this lies at the heart of a lot of signal processing. [more] [code]](http://25.media.tumblr.com/dc2b4d5c066cbd9f6022d8427fe58d8c/tumblr_mhlswzuNIY1qfg7o3o1_r1_400.gif)

The speed of the circle never changes, yet the frequencies get whack. Fourier analysis and square waves? Toooo...
