I've recently done a redesign of the major UI elements. The functionality is almost identical to what it was.
The UI, as you can now download it, has a fairly self-consistent and minimalistic look. I definitely liked it for a long time. But I kept finding that I wished that my UI looked more consistent with the default UI. You can have slick and modern unit frames and action bars, but as soon as you open up the character frame, the quest log, or one of the other default frames you see that it's not consistent.
So I took a bunch of the original Blizzard textures and used them to create the artwork for my preferred layout. This involved making backgrounds for the center console area and overlay artwork for the unit frames. I think I've come up with a really nice way to keep the layout I like while keeping the look consistent with the Blizzard default UI. Basically, it's the WoW look, but without the flaws in the default UI layout. :)
I'm posting a screenshot to see what you guys think. I really dig it, and I hope you do too. Let me know how it strikes you. There's more to the new layout than you can see in the screenshot. Particularly, I think I've finally figured out a way to make pet classes look really nice. If you guys want, I can upload more screenshots later so that you can see things in action. Tell me what you'd like to see, and I'll try to oblige.
The screenshot is clickable for a larger view, FYI.
