Check out our newest theme Acquia Slate
Our friends at TopNotchThemes have built a second theme for Acquia Drupal, our distribution of Drupal, and we've released it as a project on Drupal.org. Called Acquia Slate, it is a flexible, configurable Drupal theme with a somewhat corporate look and feel.
According to the Drupal.org usage statistics, more than 5,000 Drupal sites are using Acquia Marina, making it one of the top three most popular themes on drupal.org! A lot of effort went into Acquia Slate -- it's clean, well-documented, easy to adapt and very flexible.
It includes a configurable front page layout with a custom image and translucent menu overlay. You can quickly add you own images to the front page with a small CSS tweak and they are working on a banner image switcher to change images without any coding at all. It also has expandable graphical buttons and is cross-browser compatible.
Try it out.
