How about we try a theme without using gradients and glossy bits. I'm suggesting a theme with mostly flat colours, and using subtle transparency (care of composite-by-default) and shadows to add depth.
Just thought I'd throw an idea out there. I think the current human theme looks like a brown version of the winXP theme and the glossy, shiny themes have been done to death by Vista and OSX.
Anchor(Palette) Palette The palette for this concept is based of the colours from the African Savanna (hence the name). The main colours are still brown (the more golden end of that range) but I've also included a wider range of colours such as blue and green for highlights. This theme aims to evoke the African origins of 'Ubuntu' and to work with the hugely popular 'animal' wallpapers.

Note: the menubar in the screenshot is another concept for Hardy. I'm probably going to put a bounty up for the coding when I've written up a proper spec of what is / how it works.
