TextGlow, the Silverlight application launch by Intergen at MIX last year to great acclaim, has been released as open source under the Microsoft Public License.
TextGlow was one of the first Silverlight 2.0 applications released and it showcased many of the new features and possibilities of Office Open XML and Silverlight.
I came up with the concept of TextGlow, a Silverlight application that displays a Word document within the browser, and then had that great opportunity of being lead developer on the project and bring it to life. It was definitely a unique experience working on the Silverlight platform as it changed and matured while at the same time becoming involved in the discussion around the OOXML standard.
The source code for TextGlow has been released along with an article published at OpenXML Developer, TextGlow - View Open XML Word documents with Silverlight. The article is a high level overview of the internals of TextGlow to help developers get started with their own applications.
