I am glad to announce that after year of constant work, I have created an OS (more like a variation of Ubuntu), which I call Mundus OS, that is an extension to Ubuntu which is easier to use for a new Linux user. Mundus OS can install Windows programs, mount Macintosh dmg's, install the packages of other non-Debian Linux distributions, and is meant to be "out of the box".
The Sourceforge page is here:
The Wiki is here (which talks about the OS in full):
The screenshots are here:
I should note that the desktop and themes and updates are all Ubuntu, I have added my own software and some other softwares which make Ubuntu much easier to use for a newbie who is transitioning from Windows or Mac to Linux.
Note: This OS is not at all meant to replace Ubuntu, only to promote Ubuntu and the Open-Source community.
