    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.

Yes that's the one!! I can't believe that stuff like this can be done with so little it's just mind blowing.

Nice! You got the curvature much better than mine!
u/lewdev

I need to figure out why 1e3-(i-35)**2)**.5*9 equates to a half circle pattern.
u/KilledByAPixel

it's the pythagorean theorem! rearranged to the form (c**2-a**2)**.5 = b, you can use similar math to draw a circle
