    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.

Jus found out you can use slice insted of substring in some cases so save a char : c.width|=w=160 x.fillText(Date(x.font='5in v').slice(16),w,780) for(i=45;i--;)x.drawImage(c,X=i%9*w,Y=i/9*w,w,w,X+T(i+t)*w,Y+S(i-t)*w,w,w)
