I really like the idea of putting the app icons onto virtual shelves, just like the iBook app by Apple does this with the books, so I created a rather extensive template file with several layers:
- top bar: off, glassy or dark wood-like, can be colored by a mask layer
- shelf: off, glassy or dark wood-like, can be colored by a mask layer
- shelf perspective: off, wood-like, can be colored by a mask layer
- several shadows for the top bar and shelf
- background layer: 3 different shadows, can be colored by a mask layer
- resolution is 640x960, so it is usable both for 4th generation and downscaled to 320x480 on 3rd generation devices
By playing around with different styles I came up with some wallpapers:
The wallpapers itself should be available in the app iWallpapers HD by appwill 
very soon, just search for "shelf" or "shelves".
