Awesome gist!

Might you be willing to update it now that Mt.Gox is no longer functional?

Good idea. I've just updated it to use Bitstamp.

Hey there! We are looking to implement this into a website. Would you mind if we credited/linked back to you?

Any chance this could be updated to use their websocket API? https://www.bitstamp.net/websocket/

@bitWatcher: Yes, that'd be fine with proper attribution. I'll look into the Websockets API and, if I do implement it, I'll do it as a separate gist.
