Themes allow you to change the look and feel of your Drupal site. You can use themes contributed by others or create your own to share with the community. Contributed themes are not part of any official release and may not have optimized code/functionality for your purposes.
You can also create a sub-theme of an existing theme. A sub-theme inherits a parent theme's resources. Read more about Sub-theme structure and inheritance.
You can also view a full index of themes listing only their titles.
Kube is built with integrity and technology in mind
Kube is one of the world's most advanced and flexible CSS-frameworks. It gives you full power of choice, creativity and beauty, while handling all of the technology behind it. No more boring routine, just concentrate on something big and wonderful, and let Kube provide the rest.
Although the overall look and feel are most definitely inspired by Twitter Bootstrap, Cascade framework is not just another Bootstrap clone.

My goals with the Atomic theme are to create a base theme that provides an approachable starting point for sub themes. Atomic uses Sass and a number of Compass gems: by making a few initial global design choices, you can get up and running with some sensible defaults. Partials are broken down to let you easily provide essential base styles for elements or regions, while focusing on component styles, and keeping those styles separate from layout styles.
