I just ran across a nice free theme from the guys at eVeek.com. The theme has a nice old parchment look to it with some flashy colors. I know a few people who love this kind of stuff. They are the same ones that have monogrammed memo-pads.
The Zen menu looks really cool but a little dark and the top bar menu just looks downright cool. I love the font but I wish there was a way to not have to use it for the menus and email messages. It makes it a little annoying to read. The icons are all white on black which makes them hard to discern but they fit in perfectly with the theme.
The theme is available for free with OTA and Desktop manager downloads but you must register to be able to even see that the theme exists.
