    u(t) is called 60 times per second.
    t: Elapsed time in seconds.
    S: Shorthand for Math.sin.
    C: Shorthand for Math.cos.
    T: Shorthand for Math.tan.
    R: Function that generates rgba-strings, usage ex.: R(255, 255, 255, 0.5)
    c: A 1920x1080 canvas.
    x: A 2D context for that canvas.

There is a technique called neuroevolution (search for Evolving Virtual Creatures, by Karl Sims and also AI Learning to Walk And Run With Neuroevolution) where this kind of body movement spontaneously appears after the evolution of a genetic algorithm.
