Just in time for the holiday season -- my Polyester Christmas color scheme. In the screenshot, this theme is shown with a polyester window decoration and QtCurve widget styles with the "Shiny Glass" predefined style selected, which can be accessed by clicking on "Configure", then the "Options" button immediately above the Cancel button, hovering over "Predefined styles", and selecting "Shiny Glass, which is the next-to-last item in the popup list.
Due to the gold buttons on this, this works best if you have a widget style with buttons that has or can be set to have a shiny appearance (Keramik works well here by default). If not, you can modify the buttons to have a light gray appearance and it should look good with any widget style at all.
Enjoy, Merry Christmas, and happy 2008!
