Just looked at your progress and am very impressed!
I think they look very good and definitely better than what I have, so I had to spend quite a bit of time looking at these and decided I like this theme best.
I like the slightly mottled look, with the black background.
A themed button set like these are just the ticket, and fit entirely within the feel of the program and eq!
Also, I am interested in the On.Off buttons. As a possibility it may be doable to create a "lit on" hover over set like then a person clicks on a option/checkbox button and turns it on.
Your background is very good as it makes the buttons look rounded when in fact they are rectangular.
Some of these will be compiled into OCX controls and these will therefore be easy to use in future tools and even in my other tools as well.
You're welcome to take a shot at the main screen border graphics etc..
So far, I'm blown away..
