    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.

your code can be 87 bytes! for(c.width|=0,i=0;64>i;i++)for(j=0;64>j;j++)i*j&10*t&&x.fillRect(8*i+704,8*j+184,8,8)
