If you like to see stars or planets in our universe, Microsoft’s NUIverse (NUI is Natural User Interface and Verse is actually Universe) app might be just for you. In the video (quite a long one), you can see how user can interact with the app naturally.
I must say that the Surface 2.0 is really responsive and with the app, it looks promising. BTW, this application is designed by David Brown for the Samsung SUR40 for Microsoft Surface. Check out the video.
