That's fantastic, thank you. I'm updating it to eventually be reasonably cross-platform and cross-browser as well as mixing in things suggested in this thread, so keep an eye on that page – a GitHub link may pop up there if I get around to it, and the updates are generally posted right up on that page.

Great. Look forward to the updates.
