I came across a droid1 theme called Luna Theme. The website from the creator is here: The LUNA THEME for Android - Anthem Of The Sun
I contacted them and basically was told that he doesn't have a droid x to test the theme on and doesn't know the differences between the droid1 and the droid x. If someone who is good at porting themes over to the DX could/wants to port it they can contact him at email@example.com. I personally would donate to see this come to fruition.
Is there much interest in this theme from other fellow droid x'ers?
