I was looking into WordPress themes today and I found a few interesting sites with freely downloadable themes for WordPress 1.5.
I found one called ShadedGrey that I liked so I downloaded it and made it active. I had a couple of issues with its setup and I had to modify the files to get it to work (I had to delete the wp-blog-header.php line at the top of the files – the one it says not to delete!) but looking at the theme onscreen, I think it was worth the effort.
There are a few minor CSS issues I need to tie down still (the links are displaying too small) but I think this look is an improvement for the site.
