Live wallpapers could bring a animated scene in the background of the tablet and let you hand hae a little realistic world. I have been struggling to find a high quality live wallpapers and finally note that DualBoot Games creat "Ocean HD" app with beautiful graphics. It is stunning and fantastic for my Nexus 7.
Ocean HD is the best LWP for Android. It is my favorite live wallpaper and keep me interesting day by day.
