A few months ago I blogged about a company called Mindjet who had built OpenXML support into their mind mapping software. It allows you to visually map out your thoughts, and then you can convert that into a Word document using wordprocessingML.

Tomorrow Michael Sherotter of Mindjet is going to give a free technical "webinar" on the architecture of the Map Editor functionality. You can get all the details up on OpenXMLDeveloper: http://openxmldeveloper.org/archive/2007/01/25/1124.aspx
