I am a code novice but design junkie, and I have searched all over looking for a Wordpress theme that I can completely customize. I have FINALLY found the perfect one!! Check out Constructor 1.2.4 by Anton Shevchuk. There is nothing you can do with this theme! I use if for my personal blog and several sites I have created for friends. I was even willing to pay a little for it...but this one is FREE! Enjoy!
I am using Carrington framework with Text only theme. Customizing is easier then, if you know how to handle the framework.
