I'm not an Android user myself, but this looks ace! "This data-driven live wallpaper displays the battery level, wireless signal and number of notifications of your device in a simple visualization. It cycles through three visualizations with every unlock, and each wallpaper can be manipulated by tilting and moving the device. This simple ambient display creates a peripheral awareness of your phone's status over the course of a day." I think they've implemented it in a really beautiful way. Would love to see this (and live wallpapers in general) for iOS.

I have been using this for a few days and its surprisingly really useful. It helps me determine what my current battery percentage is a quick glance, and also lets me know if I am having a problem with my wifi!
