Stumbled upon these and thought I would share. I am actually kinda digging some of them.
You can see all of the X2 ones here
Motorola Skin, Skins for Motorola, Custom Motorola Skins
They also have some for the D3 as well.....
Motorola DROID 3 Skin, Skins for Motorola DROID 3, Custom Motorola DROID 3 Skins
but it looks like they make them for pretty much every phone out there.
And....they come with wallpapers to match the theme.
