Windows/Mac/Linux: Add clip art, advanced PDF functions, and in-editor Wikipedia searching to open source office suite OpenOffice.org with OxygenOffice Professional, a modified installation package and extension. Along with adding roughly 3,400 clip art files and templates, OxygenOffice's extensions also add support for Microsoft's Visual Basic for Applications in the Calc spreadsheet program and conversion tools for the Office Open XML format used in Office 2007. Combined with the Writer's Tools package, this gives OO.org a number of exclusive features. To install, download the extension, open OO.org, go to Tools -> Extension Manager and click the "Add" button in the My Extensions section, or download a binary to make a fresh OO.org install. OxygenOffice is a free download that runs wherever OpenOffice.org does.
