    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.

Fun looping animation. Huge thanks to the dwitter discord for helping me golf it down more than 60 characters!

An animation showing the impact of resolution and loop depth on the quality of a mandelbrot!

Show more comments…
u/Blacklink

I think that I 'may' have been able to make it draw the pattern without compression but to make it more unique I wanted to add these features which required compression
u/Blacklink

the resolution changes but also the max resolution increases over time, just as the loop depth increases over time
u/Xen

woah! that is damn impressive! i love it
