The Lorenz attractor, named for Edward N. Lorenz, is an example of a non-linear dynamic system corresponding to the long-term behavior of the Lorenz oscillator.The Lorenz oscillator is a 3-dimensional dynamical system that exhibits chaotic flow, noted for its lemniscate shape. The map shows how...

This function interprets imageData as a height-map and converts it to a random dot stereogram. A random dot stereogram is an image that can be perceived as 3-dimensional by viewing it in the proper way. For more information on random dot sterograms, see http://en.wikipedia.org/wiki/ostereograAutm...
