Kind of a silly question. I love how flexible Gnome is with its appearance, but one thing I haven't been able to do is change how a dialog looks. Just for example, if you've used XP for gaming you might have seen the Visturd Transformation Pack. I'm not scared of "getting my hands dirty"; I assume I'll need to recompile stuff, but I've not much of an idea where to look.

Not so much changing any functionality; just mess around a bit with how say the file copy dialogs look, etc etc. Purely cosmetic changes.

Thanks.
