    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.

really cool how the number of "arms" from central point, differs to the human mind over time.

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. :)
