I found a nice little Windows Vista utility to change the appearance of the Aero Glass theme even further by allowing color transformations. The normal Windows Vista style has a static color while the Vista Color Transform application may change colors over time.
The software offers a pre-defined sets of colors that have names such as Patriotic, My Eyes!! and Winter displaying small preview images of the colors that are cycled through. If you take Winter for example you see white and icy colors when you click on edit.
