Granular comes as a LiveCD, which means you don't have to install it to try it.
Granular also contains a lot of customizable themes, splashes, wallpapers, and other stuff that helps to customize Granular according to your needs. Another notable feature is the presence of two desktop environments -- KDE and Enlightenment (E17).
The K Desktop Environment is a powerful desktop environment which is extremely flexible and customizable with all the good looks. The E17 environment on the other hand is a light-weight desktop environment which is faster than KDE but less flexible than it. E17 is also known for its eye-candy and is delightful to use.
The most important aspect about Granular is that it is intended to be a community-oriented project which would derive its features from the contributing members. So we, the present members of the project, urge you to come ahead to join Team Granular and make your contribution in whatever way you can. Help improve Granular and make it the easiest to use Linux distribution.
