    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.

u/xem

amazing! how many extra bytes to have it less pixellized?
u/tomxor

Only +2 for 1/4 HD: d/18436 but your CPU will cry :P in fact full HD fits but you have to start measuring the speed in seconds per frame.

Impressive!

u/tomxor

For zoom without slowing down use k=t**t, but you will need very precise coordinates. Here are some other coords I found: f((X-50+k)/k+5100096e-9,1-(Y-28+k)/k), f((X-50+k)/k-2,1-(Y-28+k)/k+201113e-7)

Oops, hitting subpixel rendering differences again... intended for firefox, chrome looks a bit too mushy, change fill pixel to .3 for chrome.
u/joeytwiddle

Pretty nice! 😻
u/13thptr

amazing
u/tomxor

Due to subpixel rendering differences, for Chrome: see d/18346
u/Joachim

Wow! #underrated #colourful How did you make it infinite? Whenever I’ve tried making a Mandelbrot it always pixelates after the first few seconds of zoom ing in.
