HedoneDesign have a new theme called Rainbow that features 6 user customizable icons (8 on the Storm), as well as 4 predefined icons (3 for the Storm), as well as a Today Preview and WeatherBug slot. This theme is very wallpaper friendly but I recommend sticking to the rainbow background. It reminds me of some of the preloaded wallpapers from BlackBerry but with a rainbow color scheme.
