I just made this theme. It focuses on simplicity, and changes all of the icons to match that focus.
Here's a pic (Sorry it's so big):
Coming soon:
Many, many different colours (Blue, Green, etc.)
Battery colours to match.

Sorry, I didn't realize that the download had to be approved, check back in a while.
I will try to get around to icon requests, ex: iPod, Camera, etc. Just tell me what you need.
If someone can give me a ling to Dock.app that isn't dead, please PM me.
Post feedback!
