Rocket is a professional high customisable theme for those who wish their Moodle site to look less moodley. It is a fixed width theme with multiple block locations.
As this is an advanced theme using some very new Moodle 2 functions (I don't think used yet in other themes) I strongly recommend reading the documemtation via the link below.
A demo of this theme in action can be seen at http://features.demo.moodle.com.au/
Please view the sample screenshot below to see an image identifying key theme features.
Should you have issues with the using the theme, please post your comments in the forums. If you have a bug or a patch, please post these in the Moodle Tracker using the link below
