For this theme I used my custom Battery and Signal meters from my Pro 1.3 theme. They are the blue bars across the top (Battery is left, Signal is right).
The 4 smaller icons on the left are not user changable, but the 6 larger icons on the bottom are.
As you can see in the screenshots, when you scroll over Calendar or Messages your upcoming appointments or messages will appear.
