I have added a some new themes to the blog, and added a plug-in that will allow you to change between themes. I have been using a slightly customized version of Connections, but I found I wanted something without the backgound images. The current default theme is Neat!, and I like how the horsehead and flame nebulae look at the top. Also installed are Benevolence, Minima Plus, and the two default WordPress themes.
You can switch between themes using the theme switcher. As always, comments are welcome.
