Testbase theme for Office 2007 or simplfied Office 2007 user interface

Does anyone know if either of these exist? I swear I have seen one that used group policy objects & ADM snap ins.

I found the Office 2007 adms but all they allow you to do is disable objects, I want to hide/increase size/remove objects & entire tabs.

I need them for a primary school to do a proof of concept.
