My arcane mage UI is a compilation, stuff all found on WOWI and is still very much a work in progress but contains most stuff you'd ever need as a mage. It's being updated later today as I've just overhauled all the frames etc to tighten it up at hte bottom and give you more free space to see rather than real estate stolen by addons. If you don't like it "out the bag" or whatever, then you can at least use it for ideas/handy addons too I guess
