    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.

I did also play around with this.. =) I also did a shorter version where I used sin and cos directly on arc x,y instead of using rotate and translate... (didnt get exact same form so I let you guys try that on your own)

u/pythech

Funny how I came up with almost exactly same code d/8677 :D I like yours better though as it's better centered. I first thought the asymmetry made it more stylish but now I regret that choice
