Here is a hot theme from Ahead of the Curve Designs. I am using this theme right now on my 8900. The Mac Mini Theme and the icons are mini. If you like smaller icons like me then you will like this theme.

This mini edition of our OSX theme features eleven user selectable home screen icons docked neatly on a Mac like bottom dock.  The Home and Applications screens are undocked, change to your favorite wallpaper.

Again it is only for the 8900, Tour and Bold. Click here to get them.
