    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).

#hex #clock

u/f8f82804

the font is from d/11960
u/f8f82804

Each tick takes 256/1000 sec, so each pair of digits gives a value 0-255 in units of 4.66 hours, 1.092 minutes, and 0.256 seconds, respectively.
u/f8f82804

The whole clock only rolls over once every 49.71 days.

This is just the time rounded down in hours, there's a bunch of logic that could be golfed away if the clocks string was also golfed down (the first character of each emoji is the same, these also count against the 140 characters)

u/davidsharp

Darn, string should've been 🕛🕐🕑🕒🕓🕔🕕🕖🕗🕘🕙🕚
u/micahcowan

Pretty neat!The -1 doesn't work out for hours at 0 or 12. Could have added 23 (before the % 12) instead of subtracting 1 (or yeah, your string-based fix).
u/micahcowan

I think I fixed the string, and adjusted the numbers, but then undid a bunch of changes, including my string fix and adjusted the code for the broken string instead 🤦‍♂️
