I just finished tweaking up a new theme. I'm pretty happy with it. One thing I'm still trying to figure out is how to display a different number of posts on the archive/category/tag/search pages than on the home page. While two full-text posts on the home page looks pretty good, ten pages of two summaries each in search results is pretty crappy.
Edit: Issue resolved (search-fu is strong in me), but still look at the website =)
