    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.

#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.

Each line segment can have 16 directions (4 bits). The 100 line segments are encoded in 25 UTF-16 characters. Very ego-centric result, i know, i know :)
