    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.

Storing the gfx data like that is sweet! So nice to see if without obfuscation!
u/BriSeven

if you deduplicate the symmetry, rotate it (so that it is 8 rows of 16 pixels), and prune out the two rows that then are just zeros... we can shave the graphics data all the way down to 鰜鹞廾皶㜷彟
u/BriSeven

which would be worth it if you can find a way to undo all that which isn't more code than the characters we save
