Nice themes everyone! Here's mine, a compilation of several different pics I've found online and wherevs. Its called Pink and Blue, and as you might guess, consists of predominantly pink and blue wallpapers and stuff. By default the Glass is set to the "Blush" color, a very light and transparent Pink, but it plays nicely with clear, light, blue glass as well. I never thought I'd have a pinkish theme, but after installing that japan one with the cherry blossoms, I quite liked it. You may also notice I use a slightly larger mouse pointer size, and I reduce the size of the minimize/maximize/close buttons, for I really dont like the titlebar being thick and stuff, its not so pretty and a waste of space imo :P.
Unfortunately, the pic doesn't show the better wallpapers, but here ya go: Theme
