Hrmmm... i don't really like any of the themes, but that's just my personal taste. I'm a minimalist that likes the color flat black for my desktop interface without the gothic/industrial/spooky touch.

However, instead of complaining I'm working on my own project (slowly but surely) that I hope to upload whenever I can be satisfied with it. That way those that share my taste can find something that they like.

If you can't find anything you like, make something, and post it so if there is somebody like you they'll be able to find something that catches their eye.
