What to do and what not to do GUI sites:
http://www.asktog.com/columns/022Design ... Fitts.html(very good, if you're making a GUI, READ THIS!)
http://axp16.iie.org.mx/Monitor/v01n03/ar_ihc2.htm(good)
Jordan_C has a GREAT idea, download a program that allows you to skin Windows:
http://windowblinds.net/ (get Window Blinds for Win9x and XP)
http://www.stardock.com/products/skinstudio/ (make skins for Window Blinds)
http://www.tgtsoft.com (get Styles XP, only for WinXP, but better than Window Blinds, there is also a free version of it called UXThemeUtil)
Hope that helps you,
