OpenOffice.org is not just a website, but is a complete office suite of productivity. It is compatible with files created by Microsoft Office. The actual website will allow for a totally free download. Templates are created by users and shared there are used for every purpose possible.
Currently, we have worked with following programs contained in OpenOffice.ore with our classes:

Later on, expect Impress to be added to this demonstration.
OpenOffice.org is open source, and open to distribute anywhere around the world. The newest version is always updated free.
