    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)

Cool! how about a texture on it? for(j=w=c.width|=N=60,x.fillRect(68,N,18,w);j--;x.fillRect(X+4*(X*Y/8e3)+90,Y+X/9*S(Y/N+X/N-7*t)+70,s=(X|Y)%256*.06,s))X=j%N*15,Y=j/N*15
