    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.

Thanks for bringing up JOY DIVISION on Slack - https://www.dwitter.net/d/2108 is super well done as well.
u/magna

Is there a Slack for Dwitter?

There is a general JS golf slack with a lot of dweeters in it at jsgolf.club
