Thanks for the replies everyone

The mods are:
Twobox Toolkit (although you don't really see it)
Spartan UI, mostly unmoded which uses Bartender4
Itemrack
Pitbull(a little of) I'm still integrating (again, barely seen)
Yury's Rune Display - I had to get into the xml and turn what was a smiley face upside-down to make put it on top the center circle.
The buttons themselves are just made by selecting the appropriate ones from the /macro menu

Also using synergy with broadcast, although I'm not entirely happy with it and thinking I'm going to mod it some.

I can do it this way because I don't plan on two-boxing others. Snowfox and Snowyknight are intricately linked.

Edit: Oh yes, also Mik's scrolling combat text - that's the circular "hud"
