    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)

There is even room for a bigger font: for(x.fillRect(0,0,z=i=2e3,i);i--;x.font='1cm o')x.fillStyle=R(0,i,x.fillText(String.fromCharCode(0x30a1+i%99),97*i%z,(i*i+t*i)%z),i+.1)
