    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.

I like this trick of re-using the same args for moveTo and arc back to back. The first two args are x and y for both and moveTo ignores extra args.

Cool function from u/ntsutae, but mostly tinkering with the rendering logic so its quick and short. Takes about a second.
u/pavel

Renders f on -1<=x<=1 and -9/16<=y<=9/16
u/pavel

Expects 0<=f(x,y)<=1 in that range
u/pavel

...or alternatively -1<=f(x,y)<=0 in that range too as my code is doing...
u/pavel

i can be initialized to whatever you want, it is a pure speed vs lag tradeoff
u/taupelink

wow!

NICE! - Interestingly this code f=(X,Y,n=98)=>Y*Y>n?n:f(4*X*Y-.5,Y*Y-X*X,n+1.2) from d/19821 produces an image with many similarities with this.

DANG this is speedy! - you can crank out some fractals in no time :-) f=(X,Y,n=1)=>X*X>n?n:f(4*X*Y-.5,Y*Y-X*X,n+1.2) for(i=5e4;t<1&&i--;x.fillRect(X=u&2047,u>>11,19/f(X/960-1,u/2e6-.56),1))u=-~u
