    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.

Wait? How did you get 145 characters?
u/pangolin

It says 140/140 for me. If you copy it into notepad++ or something I think it counts linebreaks as 2, Dwitter counts linebreaks as 1.
u/recursive

If you edit it, suddenly the character count becomes correct also.
