Developers Developers Developers! No it's not Steve Ballmer this time but Tim James over from EMC Consulting who is commanding the attention of Windows Phone Developers. He's provided a detailed tutorial on how to give maps the 3D dimension. The trick is wrapping the map around a sphere allowing the user to swipe around to get the feel of the extra dimension. Tim has provided a complete instruction set in his blog over here.

On similar lines is the application Stars 3D (opens Zune). This app (available in the Market Place) uses a similar ideology, but instead of locations on earth it presents stars in over the earth (a transparent sphere). It has views for constellations, planets and stars and latitude-longitude view. And don't worry if you didn't understand much from the video (below) because a help button is present in the app.
Here's the link to the Stars 3D application video
