    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.

You could consider Math.PI = 22/7

When I have chars left I sometimes write out the full precision constants.

Replaced the dot with the "FOUR-PER-EM SPACE" unicode character #short #default #unicode

u/katkip

Oh, thanks
u/jylikangas

Isn't it even shorter without the second repeat call. I mean just adding the vertical parts inside the string
