We're currently calling the plugin JNovaContact. I think we'll also add a 'loading' animation and some template options in the plugin parameters soon.
One of things about this that I really like about the plugin is that it uses the existing contact information in your Joomla! installation - great for keeping things lightweight and staying 'close' to the core installation.
The Plugin is JQuery-based, and still very early in development. Try it out and let me know what you think! - emails go to our office.
PS. I know the form is clearing our right-column. Like I said, the plugin is only ALPHA :)
