    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.

Holiday glass, using an adaptation of new_core's iteration on the colour palette trick, which I was able to shave down further to x.fillStyle=R((d=119*i)%256,d/1.4%256,d/7%256)
