    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.

My first attempt to draw a Mandelbrot fractal, straight from the reference implementation from Wikipedia. Still need to learn lots of size/speed hacks, apparently :)

Instead of r*r+j*j<4 you can use just r<4 , that's 6 characters less. In this low resolution there's no visible difference.
