I would like to know if there are any examples, tutorial on how to
completely change an application's look and feel.  By that I mean the
colors, the way menus are drawn, the way tool bar items are spaced in a
tool bar, the way tab identifiers are shaped, etc., etc.

There are a few interesting 'LAFs' such as MS Money 2005, MSN Messenger
6.2, Office 2003...just to name a few basic ones.  I would like to have
one of my graphic designer friends do a mock up in photoshop then
produce an application that looks like it (I'm assuming it all has to
be done programatically so designers would have to resort to something
like photoshop).

I also understand that part of the reason the aforementioned
applications look the way they do is because of controls which are not
available publicly...despite that, if designer can create websites
(with primitive components) that can draw powerful and diverse
emotional reactions, I don't understand why rich client GUIs have to
look so ugly and gray (obviously 'consistency' has its place too).

Any way, it will be even better if someone can point me to publicly
available LAFs, the way we are starting to see them for the Java/SWING
community.

Thanks!
