    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.

Twisted Cylinder #beesandbombs

u/pavel

Single stroke call and only ellipse to draw. The lines are canvas connecting the various ellipse draw cal into a single stroke, I just manage the start angles.
u/pavel

o determines which ellipse, 0 is top and 1 is bottom. It goes: top, bottom, bottom, top. Four-cycle to draw two vertical lines and reset. The angle increments every 2 so top and bottom angle is the same.
