January 6, 2012 Update
German and Italian translations of the demo are currently in production.
We need someone to help with graphically editing the GUI buttons, and things like that for the Italian translation. I already have a list of the Italian equivalents of the English words given to me by the Italian translator. So you don't even have to know Italian to do it - just be willing to help.
If anybody wants to help beta-test or proofread these translations or wants to help make a translation into another language - let me know.
