    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.

Nice! I tried sonting similar, some time ago, but could not golf it and still make it look good -> this is how far i got (uncompressed): with(x)t||(a=[1,1],translate(960,540)),a.push(o=a.at(-2)+a.at(-1)),strokeRect(0,0,o,o),arc(0,o,o,4.7,0),translate(o,o),stroke(),rotate(1.57)
