    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.

Beenary Clock

u/tomxor

4 levels of geek - bees, beenary representation, beenary segmentation of 1 rotation of the hive into 2**16 (the lowest bee counts ~1.32s increments aka "bees"), based on the apiformes epoch (no leap bees, no queen zones, no hivelight saving bees, yes... it will gradually drift out of sync with the hive's rotation, currently by 20.48 bees or 27 "seconds" in old humanoid time. When the difference approaches 2**15 bees it is speculated honeygeddon will occur, or perhaps more realistically an aristocratic upheaval and abolishment of apiformes epoch based bee keeping).

Variant where the distance scale factor is 1/2 plus-or-minus a little bit. Also some code golfing

u/taupelink

I think some of the pattern details are an artifact of the way I golfed the code...of whatever the values of sin(i*540 radians) are, for integers i=0,...,539
