...answer.)
var seed = 1;
function random() {
var x = Math.sin(seed++) * 10000;
return x - Math.floor(x);
}
You can set seed to be any number, just avoid zero (or any multiple of Math.PI).
The elegance of this solution, in my opinion, comes from the lack of any "magic" numbers (besides 1000...

Why doesn't GCC optimize a*a*a*a*a*a to (a*a*a)*(a*a*a)?
... the obvious answer is to precompute it once (Knuth provides a table up to 100) and use that hardcoded table (that's what gcc does internally for powi).
