    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.

I shaved off 12 more chars for(i=4e3;X=--i>>1;x.fillRect(X,Y,1,X+Y+8*i&8))Y=60*t,x.fillStyle=['#D23','#24A',R(),'#FF0'][0x66ba6545>>((i%2?Y:X)/16&30)&3]
