Google introduces a number of Live Cases, accessories that attach to a set of Android devices and provide NFC-based content and abilities. This first case includes a button that allows you to launch apps. It also allows you to connect (with NFC) to content through the case. In this edition, that means getting some stuff made in collaboration with the musical artist Skrillex. Sound like a good deal to you? Or do you need a live wallpaper to go with that as well? Because you'll get that too.
