    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.

Replace q with 2, 2.0003, 3, 4, 5, 6, 7 ... 9876 and get 3D shapes of PI with X+Y simmetry

#uberquine because it shows the code to render what it also renders

u/username

an uberquinequine would be what also shows the code that renders the uberquine, however, that would not be an uberquine anymore and look bad. would be easy to do it here, however, too dull
