    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.

Also fixes some glitches in the original
u/keithclark

swap ,k=r>>8,k for ,r>>=8,r to save a byte (97)
u/keithclark

also r=900/(4-(t+j/9)%4) => r=j/(4-(t+j/9)%4) (94)
