Today I updated mrlsmath.com to use the WordPress Suffusion theme.
This is a free theme and can be found here:
Here’s the blurb from the WordPress.org site: http://wordpress.org/extend/themes/suffusion

It supports Mega-Menus, custom layout templates, advanced support for custom post types, customizable drop-down menus, featured sliders, tabbed sidebars, a magazine layout and lots of enhanced widgets for Twitter, Flickr, Google etc. It has 19 widget areas, one-column, two-column and three-column responsive, fixed-width and flexible-width layouts, 9 pre-defined templates and 19 pre-defined color schemes.
