I've modified an existing theme that I originally created for (don't laugh) pMachine. It's been modified for MT and Blogger, but only now have I attempted to dress it up for WordPress.
It is here:
The theme is called Orange Tulips. Once I get some positive feedback (i.e., once I determine it isn't misbehaving terribly), I'll offer the files in a Zip set and post that here as well.
Thanks for looking and let me know of any problems you encounter while viewing it.
