    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 :)
