    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.

Cool, that almost looks like 3D!
u/lionleaf

This doesn't work on my Macbook with chrome for some reason.
u/New_Core

can it be the translation? if you put 0 in last number of translation and set the last number in code to 500, do you see something then,, or remove the translation and keep the 500 at the end of code,
u/lionleaf

Turns out any font size above 250 doesn't show up. 250 works fine though. Nice effect!

u/iverjo

Here's one that draws faster: for(i=4;i--;){for(j=1080;j--;a=b=0){for(k=35;k--&&a*a+b*b<4;a=y,l=t*240+i)y=a*a-b*b+l/540-2,b=2*a*b+j/540-1;x.fillRect(l,j,1,S(k/9))}}

Nvm, they depend on various variables being defined. I was fooled.

How about colors? t?i++:i=0;for(j=1080;j--;){a=b=0;k=35;for(;k--&&a*a+b*b<4;)c=a*a-b*b+i/540-2,b=2*a*b+j/540-1,a=c;x.fillStyle=R(k,j,i);x.fillRect(i,j,1,S(k/9))}
