    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.

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.
u/katkip

Great job bro!! I love this one!

In 140, with #lighting/#shading? Amazing!
u/yonatan

Thanks, not very fishy tho (the shading). Most of the 44 extra bytes in the compressed version were the XY rotation.

Some #fish are black and white. Just not the ones in camera adverts and holiday brochures ;-)

@joey - it's not the color that bothers me, it's the lack of (specular) scales

Will throw 7 if the decryption works correctly. #slow
u/katkip

it lags so much
u/f8f82804

it should be possible to optimize the modular inversion and exponentiation, but it would probably go over the character limit
