HedoneDesign have a nice theme up called Digital. The icons look really slick and you can get 8 additional wallpapers in the Expansion Pack.
Higher models (8900, 9000, 9500 and 9600 series) can toggle the homescreen’s navigation panel. By closing the panel, you can enjoy the background wallpaper in all its splendor. This theme also allows for quick navigation to regularly used items such as the Clock, Options and Manage Network Connections.
