    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.

Outstanding. Your motivating me to up my game. How much of your work is trial and error about what looks cool vs actual engineering?
u/cantelope

artfarnaa, thanks. it's mostly just educated guesses. Most of my dweets start as a pretty concrete idea, then I draw from experience and do my best to fit the idea into 140b. Sometimes I'm successful, and sometimes not. :)
