    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.

#growth of ice crystals

I used a golf trick to plot for only 2 seconds: x.fillRect(...,...,...,t<2). If time >2 then the pixel height will be zero.

Nice idea, but it became annoying after a while ^^ I had to edit the code to a syntax error
