    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.

Looks very nice and smart coded. One noob question: which colors will be used in the loop by default when you don't use fillStyle? I saw many examples without fillStyle but the result is not monochrom. Thx.
u/rep_movsd

The default fill color and stroke color are black. Colors have to be set with fillStyle, strokeStyle or perhaps even setting the background (rare)
u/pavel

The default color for fill, fillRect, stroke, strokeRect is black and you need to call fillStyle or strokeStyle respectively. You must have seen other drawing techniques, maybe like putImage or using style attributes to add a filter over the B&W colors.
u/pavel

Haha looks like we answered at the same time and eerily similarly.
u/UEZ

Hmm, when I look to https://www.dwitter.net/d/23732 I cannot see any strokeStyle/fillStyle but the color result is greyscale.
u/pavel

Gray can be achieved by spacing out black pixels amongst white ones. d/23773 shows this clearest.

u/rep_movsd

Try swapping around the r, g and b values - b, g , r and g, r, r look pretty realistic

u/rep_movsd please paste the colors (q=...?) that you found so I can try your suggested combinations, thanks!
