    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.

create your own glyph with d/11967
u/metamero

there is an error in this code. replace to i=-1; so it can draw the first pixel

Omitting the space in 99%50% does not work in Safari, everything is black.
u/f8f82804

yeah safari stinks

try "for(c.width|=i=384;i--;x.fillRect(960-w/2+e,4*i,w+e,4))y=i/80-2,w=y>.7?3e3:(1-y*y)**.5*640,e=T(t/9+i*w),x.fillStyle=hsl(${-y}rad 99% 50%)" which should work and is still <140

this one doesn’t even need the fillrule. Was just looking into other cycloids and Lissajous figures, only to end up with a circle.

You've reached the end.
