    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 like all-grey on iOS...not sure what's going on
u/taupelink

I think it has to do with the fillRect function and fractional widths. I wonder whether tiny widths get rounded up in iOS, filling in blanks that appear on other systems

Thanks to everyone, and perhaps especially donbright, we have enough space for colors! (I just copied the fillStyle from cantelope's #2451 )

u/Woodmouth

t?x.fillRect(a+=9*S(d),b+=9*C(d),9,9):(b=a=99,d=0);d+=Math.random()-.5;d=b>1080?3:(b<0?0:(a>1920?5:(a<0?2:d)));x.fillStyle=hsl(${t*99},99%,50%
u/Woodmouth

4 characters away from colors and boarder btw
u/donbright

@joeytwiddle was correct, you can take the parenthesis out of my ? statements which should leave enough room
