Known only as the App Wall, this first implementation of a 9-panel LCD touch-screen app store showcases apps from Verizon's VCast catalog. Envisioned for retail stores, for instance, you tap your way through categories and apps to surface a nugget of information about the app, and a QR code for downloading it on the spot. Playing with the wall is fun. Tap and drag the screen and the top layers of the concentric circles move with you, adding in some 3D perspective--up to a point.
