I've written a JavaScript-based Fifteen puzzle which integrates a timer and supports different puzzle sizes. I created it for my personal use but it might come in handy to some of you:

That is very nice and you should make a thread about it.
The only thing I dont like about is is how the space moves, I think it should move in the direction you press instead of opposite.
