For many of us, the best part of having an Android phone is the user customization it allows. It's odd then, that there is no easy method to change the theme on your phone like there is with other phones, ala BlackBerry. Hopefully, this is something that gets sorted out in future versions of Android, as Google has let it be known that a unified UI is on their agenda.
In the meantime, sprintgirl from the Android Central forums has worked up an excellent tutorial for those who are rooted and feel like being creative. While this particular lesson is based on the Sprint Evo 4G, the tools and general ideas are the same for all Android phones. Have a look and see if you can create the next masterpiece!
