I was tired of seeing my mIRC windows in that horrid blue color,
so I decided to modify the aero visual style to make it have gray borders.
I couldn't figure out how to tell which images were the ones for the basic windows,
so I just created a batch action script in photoshop to make ALL of them gray.
After that I restored a bunch of images which looked better in full color, and this is the result.

(the glass borders look blueish because of the water in my wallpaper)
NOTE 1: I haven't managed to change the visual style names. I have looked through a few other themes and they all seem to use the original names, so either it's too hard to change, or it can't be done.
NOTE 2: The theme is based on the 64bit visual style, so I guess it only works on vista 64.
EDIT: I added the transparent when maximized" patch from VistaGlazz to the theme, so here you have AeroNoBlue2.
