    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.

sorry the comment went so far right, not sure what happened. but basically it is a 140 char version with e22 for red. nice flag!

nice!
u/sfz

I think also instead of x.Q= you can just do Q=
