    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.

Gemstones for only 1 byte? That's a bargain! Although I notice the background now turns yellow for half of the rotation. What a curious bug! I haven't investigated the code.

Gemstones for 1 byte is crazy

jewel encrusted?

Yeah the background is set by a fillRect(0,0,n=m=15e3,m) call in the beginning. The fillStyle will be whatever fillStyle was set to by the last fillStyle call in the for loop "R(r=b>0?n*m:k,r+r*(C(6*s)-C(n/133)))". When n=0 for the last one, this will alternate between black and dark yellow depending on b>0, which is related to the rotation of the crown.
