    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.

Super Tiny Fractal Part 2

u/DataMeta

#dither #fractal
u/joeytwiddle

Very nice #tiny
u/username

it is not a fractal though
u/KilledByAPixel

It is though... Also interesting if you change the ^ to a | or & it becomes an ordinary sierpinski triangle (also a fractal).
u/username

I agree with the Sierpinski triangle, but the other one is not a fractal on my screen.
