UniveRSS is a showcase application that demonstrates the use of several WPF features, 3D animations, data binding, and data visualization. Currently UniveRSS uses the RSS Feed Store managed through Internet Explorer 7. Later versions will allow you to manage the Feed Store from within the UniveRSS application.

It looks very nice and very much the type of thing I envisage in Second Life, when (and if) we get html on a prim surface. With all the available data bindings and communications we have at our disposal there, it should be faily easy to build this in the Metaverse.
