Two days a week? What we will think of next?
I came across this cool brown theme Solipsus and just couldn't wait for you guys to try it out. This theme comes courtesy of the talented Tiffany Nguyen (Rikkye) and I've updated it to support widgets as well. (Though the sidebar can look funny with some types of widgets.)
Update: Chalk it up to 2 AM silliness, but last night I forgot to "activate" the theme for you guys after deploying it. You shoudl be able to find it under your Presentation tab now. Sorry!
