    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.

115 bytes: for(j=1080;j--;a=b=0){for(k=35;k--&&a*a+b*b<4;a=y)y=a*a-b*b+t*60/540-2,b=2*a*b+j/540-1;x.fillRect(t*60,j,1,S(k/9))}

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))}}
u/iverjo

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

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))}

Nice enhancement myJS!
