EarthlingTwo is the 2nd HTML/CSS template we have converted to a Drupal theme that was designed by NodeThirtyThree and templated by FreeCSSTempaltes.org. NodeThirtyThree has some pretty sick open source CSS template designs and we are looking to convert as many of their designs as we can to Creative Commons Drupal themes. The theme is currently Drupal 6 only, but we hope to soon have a Drupal 7 release ready also.
Check out a demo of the EarthlingTwo Drupal theme.
Please file any issues or feature requests in the EarthlingTwo Github Issue queue.
Thanks and Enjoy the Drupal EarthlingTwo theme!
