I have changed the wordpress blog theme to the MistyLook theme, and added a custom header. I think it looks more professional, is easier to read and more relaxing than the standard Kubrick theme. It is also more relaxing and more in keeping with the mood I want to create.
Changing themes was dead easy, I am really impressed with the usability of wordpress. You pick a theme, preview your site with the new theme and then make customisations to it. The Header includes a picture of my Mandir, some of the murtis and a nice Nataraja picture that I liked.
