    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.

Great!! Love fractals!! Also, I was hoping to see more dweets using Path2D, I think there's lots os great possibilities in there.
u/sigveseb

Very nice! And shh, Path2D is the hidden secret of the canvas api :D
u/sigveseb

But yeah, can't wait to see more Path2D dweets :)

What does ~~ do? Like in (~~a?h:a*h)
u/Renaud___

It work as a math.floor. actually there is a difference but i dont remember how exactly
u/Renaud___

Dunno what changed in Chrome recently, but now this animation is very very slow :(

u/noonat

~ is a bitwise not. It flips all the bits in the number to the opposite. Flipping again (~~) puts the bits back to what they were. It works does something similar to floor because it truncates floats to 32-bit integers as part of the operation. (But unlike floor, ~~-2.1 is -2 instead of -3.)
