Presumably nothing, as he has quit the game.
I suppose I could not be a total jackass, though, and repost:
url=http://postimage.org/image/ar6qkrok/full/Rico touched on this above and a lot of people are really bad at it: having things set to the same font/bar texture is really important for a nice-looking UI. I use a pixelfont for all unit frames and unit-framey things like cast bars, nameplates and combat text because it's easy to read on them and the numbers are (generally) monospaced. Chat log uses a different font, as does tooltip. Almost everything uses the same texture. You can't see it in this screenshot but the pixelfont I use punishes people who put accent marks in their name because it can't display them, so their names render all fucked up.
Unit/target frames are in the center of the screen because they're fucking important, you WotLK-spoiled plebians. I don't display my own name/level/race/class on my player frame because I'm not a moron, just hp/mana text. Stuf uses the default holy power frame, detached and movable, and it looks a touch out of place but I've grown to like it. Debuffs are on the left side of my frame, while a very small set of buffs are on the bottom left (things like Righteous Fury or Divine Shield). Long term class buffs like Fort or Might aren't shown at all.
Target frame is mostly mirrored, except the target's name is displayed, and underneath it is ToT. A limitation of Stuf means I have to leave the mana bar in the ToT frame; generally this is not relevant information, but it's a minor quibble.
Cast bars are located above player/target frames. I'm still iterating a bit on these; things like orientation of target cast (should be reversed to match unit frame orientation, but not sure I like it) and color (probably going to be brighter) but the size is not really a problem if you are looking where you should (center).
Above playerframe is clcbpt, a very simple Judgements of the Pure/Beacon of Light tracker.
Grid is nothing special. Larger frames than I've run in the past to give me more room to work with indicators. And having mana bars on Grid might be useful in Cata but is stupid now, so you shouldn't do it.
MSBT uses the same pixelfont that my frames do, though I've moved the incoming/outgoing to the sides a bit because the default settings are highly claustrophobic. Icons and extended skill names are turned off. Skill cooldown notifications are left on because they're useful from time to time, though I may end up turning them off still.
Skill bars on the bottom are there because they are the best overall display of ability information: a cooldown monitor gives you cooldowns but not range/mana limitations, et cetera.
A simple LDB broker is below that, with (left-to-right) mail indicator (I almost never check the minimap), durability, FPS (kind of useless, probably disabling), latency (very important to have a headsup on my connection about to shit itself), UI memory (also kind of useless, really), local/server time, and dungeon finder icon.
Not pictured: OPie, the best addon.
