DRop down login box

It is currently in use on the website, http://diythemes.com/thesis/about.

If anyone knows what plugin, the webmaster(s) is using please let me know so I can use it for my own website http://www.dreamsinplay.org.

The website also has not just a custom login screen, but also implemented it into their wordpress theme which I have not seen done anywhere else!!!!

Thanks,
Andrew
