just some design thoughts....
I was always a big fan of some of the "wrap around" UI's from EQ1 - if memory serves, our very own Cairenn had a very nice Celtic-Themed one that "framed" the screen all the way around... I'll have to go over to eqinterface and take a look around - its been a while
also, I was looking at the LoN UI and I really like the way the left side menu "slides out" from the frame on mouseover - keeps things tidy while making it very easy to get at more info when wanted.
