Gizmodo offers a preview about the new ZenZui interface from Microsoft.
ZenZui's Zooming User Interface organizes Web and user content in 36 tiles arranged in a virtual desktop grid. The desktop can be panned and zoomed in or out using the cellphone's touch-screen or numeric keypad. Then, when you activate one of the tiles, it will show you a small interface, which appears to follow the same directional pad control for user interaction.
