Remember TouchXperience? It’s currently in a closed beta testing phase, but Schaps, the developer, posted an interesting video of the snazzy, unreleased Windows Phone UI. It shows how users can customize the background with all kinds of wallpapers. Most notable, of course, are the “Interactive Backgrounds” that act just like Live Wallpapers on Android. In the video below, we get a glimpse of Album Artwork, Animated Circles, Animated Icons, Animated Sky, Earth, Google Maps, Nexus One, Plasma, and Xbox interactive wallpapers. The eye-candy of the UI is certainly impressive, but let’s hope we see a public release soon.
