    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.

how the actual flip did you get 232 characters in there
u/KilledByAPixel

416 bytes, 140 characters ;)
u/tomxor

Or 140 unicode code-points (how the server evaluates length), 232 UTF16 chars (how JS in the browser evals length), and 198 effective bytes (134 chars provided by the escape compressor as 2 bytes per surrogate pair, and 60 bytes in the image manually packed into the string "o" with 20 bits per surrogate pair + 4 chars for variable assignment outside)... :) yay i'm learning about arcane UTF16 stuff.
