Need to Update Site Design

I'm thinking I need to overhaul the look of this site. The current look is essentially the same since June '05 when I released Cameron's Thoughts 2.0, I'd like this to be more along the lines of Cameron's Thoughts 2.1. I don't want to make any underlying changes to the site, just something to update the CSS and maybe some minor content and layout changes. If anyone has any suggestions, please let me know.
