Microformats are about enhancing the web, representing data in HTML and moving that data around. Oomph: A Microformats Toolkit is for web developers, designers and users, making it easier to create, consume, and style Microformats.

Oomph is an amalgamation of applications: an Internet Explorer Add-in built in C++ that finds Microformats on a page; a cross-browser HTML overlay built using JQuery that aggregates Microformats; a set of beautiful CSS styles for Microformats; and a Windows Live Writer plug-in written in WinForms for inserting hCards. And, the entire project is up on Codeplex, ready for community contribution and extensibility.
You can find more information about Oomph, see the articles and video at Mix Online; Oomph is available for download at CodePlex under Microsoft Public License (Ms-PL).
