Critters is a Twenty Ten Child Theme for WordPress
(If you would like a custom theme of your own, email deltina at socialmediapower.com.)
Critters is a refreshing and clean Twenty Ten child theme with five original headers based on the nature photography of Deltina Hay. You can also use your own custom header.
A WordPress child theme is a theme that inherits all of the features and functionality of its parent theme, while maintaining a custom look and feel. Social Media Power chose to create child themes using the WordPress default theme, Twenty Ten, because it is a theme that is regularly updated and has many nice features.
You will need to have the latest version of the Twenty Ten theme in order to use the Critters child theme (this theme comes with any WordPress installs of 3.0 or later). You can download the Critters theme from the WordPress directory (link available here once theme is in the directory), or from this link.
Here is a good tutorial on how to install a child theme.
Here are some screen shots of the Critters theme, featuring all five custom headers:
