'Gos', and 'Regex File Renaming Utility'

Gos

Gos is a Linux build that fully integrates Google; in the words of the developers, "Our idea is to be a simple, user friendly, beautiful desktop for normal people. Out of the box, just works! We're creating an OS ecosystem that is complete. We come with all the software you need to browse the web, email, instant message play movies, music, and connect to iPods create and edit documents, spreadsheets, presentations, databases, images out of the box. Plug and play! We recommend Google for just about everything Gmail, Gtalk, Calendar, Maps, Docs and spreadsheets, and more. We'd like to welcome you to the idea that Google already is your operating system."
