Google Voice Click-to-call Widget

I'll keep this short. I was lucky enough to get in on the Google Voice closed beta (back when it was Grand Central). It offers a free click-to-call widget that you can embed in your web pages. But it didn't offer quite enough "pizzaz" for my taste, so I enhanced it a bit using some Javascript. I'm making the code freely available. (It should be an interesting read.)

It works in IE 6 through 8 as well as Firefox 3 and Safari 3. I didn't test it in anything else. To see it in action, use one of the aforementioned browsers and go to http://techhead.biz.

Feel free to use it, improve it, etc. As always, a little credit here would be appreciated. If you do use it, please leave a comment here and drop a link so I can find you.
