    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.

If someone can squeeze in a hard shadow and a purple grid we will be done.

I distinctly remember the grid to be blue... but all the youtube videos shows it to be purple... I think it's a conspiracy :-)

I can't find it now but I seem to remember reading about how emulated colours of amigas look different from real amiga video output. The emulators are probably just spitting out the RGB values and letting the host OS do the gamma etc. I suspect real amiga video output must have been a bit "coloured" which causes this difference.
