Very nice-looking UI, it holds that sci-fi/FPS feel. Sleek gradients galore, although some parts of the screen seem to be invaded by unnecessary black gradients or panels, which stick out a bit.

Other than that, great work! :)

Sneak Peak 1.5!
 

Woah, those new screenshots look pretty damn sexy to me.

Hey :) I'm using your UI and im loving it! But as a healer I need to have the raidframes somewhere near the center of my screen. Thats the reason why I use grid additional to the arpUIs raidframes.
Is there any possibility to move and size the raidframes?
(sorry for my bad english)
