    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.

Tip: Hijack an existing variable that you don't make use of (like S, C, T) to avoid the initial reference error for the variable E

4 point sierpinski attractor :o - If your PC can handle it try pumping up that N=1e4 and making the points smaller

Set it to 2e4 and 3x3 points. Looks really cool!
