This is a replacement for the default Enlightened Theme. I've only made simple improvements to it, so it should drop right in to a layout that uses the Enlightened Theme and leave it completely intact.
Most of the work was to remove the gradients, modernize the buttons and accent colors, and remove much of the default grey. I originally posted it in New and Improved Enlightened Theme! and thought it would be good to bring it to the attention of this group. (thanks for the suggestion RosemaryTietge!)
I have some more free themes I have kicking around that I intend to release to the community for free. I'd love to hear what people think!
