    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.

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)

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).

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 🤦‍♂️
