    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.

Single vulture: for(c.width=i=300;i-->-4;)x[f='fillRect'](i,99-C(i/31)*9,.5,S(i/89)*9),i<5&&x[f](X=99-C(t+=i/59)*(90+i*5),X/9+C(t*4)*i**2/5,s=7+!i*4,s-5)

Nice trick with the flipped drawImage!
u/jylikangas

Thanks! Here's two vultures without compression... 'for(c.width=i=-9;i++;)x.fillRect(X=99-C(t-=T/59)*(90+i*5),X/9+C(t*4)*(T=i+4)**2/5,5+(s=2+!T*4),s) x.scale(-.5,1) x.drawImage(c,-290,50)'
u/yonatan

Here's a whol bunch of 'em for(c.width=i=-9;i++<9;)i<0?x.fillRect(X=99-C(t-=T/59)*(90+i*5),X/9+C(t*4)*(T=i+4)**2/5,5+(s=2+!T*4),s):x.scale(-.9,.9)|x.drawImage(c,-290,50)

Save a char by moving the fillRect call into the loop body to avoid ;
u/yonatan

you're right!
u/keithclark

it's also better to use rect height for the "alpha", avoids the jagged edges on the right. for(i=c.width=99;i--;)for(j=56;j--;)x.fillRect(i,j,1,(S(j*j+i/j-t*7)+C(j**5-i/j*6+t)**3)*j/99)

Scanline Rainbow Mandelbrot Section

Show more comments…
u/rbong

I've spent quite a bit of time now trying to get a faster, more detailed mandelbrot set or other interesting fractal that hasn't been done in fewer characters. This has included exploring obscure fractals like those generated from polynomial roots, using image data as storage or other memoization, and the dweet earlier that used WebAssembly with a new compression technique. I'll keep exploring these ideas, but this experiment bore the quickest result. #fractal #mandelbrot #scanline #rainbow
u/rbong

Oh yeah, I also tried MAndelbrot perturbation. It's pretty expensive for these purposes but I might be able to do something similar.
u/Xen

Love it!
u/tomxor

I'd love to see more fractals, especially more esoteric ones, keep up the good work rbong.
