Pondera of the Blackhand-US server sent in his UI, along with a short description of the major addons he's using. One of the major decisions in shaping this UI was to make it viable for each of his alts, something I strive towards with my own UI. Pondera is a 26 year-old Web Developer from Brazil, which shows in his UI. (Note the aesthetics and organization.)
As you can tell, his setup is similar to many UI's you'll find out there, with much of the game function happening at the bottom, and a compliment of information "gauges' at the top, courtesy of Fubar. I'm not sure what skin he's using for his "Fu-stuff", but I'm digging it myself. Note where Control Freak, his consumables and Decursive are. I like that he's found a home for those in the nooks and crannies of his UI, although I would imagine that Decursive could be problematic in that location when running Alterac Valley.
Check back after the break for his addons and description.
