As much as I love Visual Studio, I am not a huge fan of the default theme. Something about staring into a lightbulb on high bright all day that makes me think it can’t be too healthy. Whenever I can, I change my theme to a darker one. Previously this meant heading out to google to find some one off themes, but not anymore.
There is a new theme repository site out there that not only lists themes, but lets you create your own in real-time. It looks like there is already a handful of styles up already and it is growing every day. It also has the ability to generate the themes for Visual Studio 2005, 2008 and 2010. Really cool stuff.
