Morphix is a derivative of Knoppix, another live CD distribution. Morphix is modular; this means that it consists of a number of parts which together form a working distribution. What does this mean to a normal user? Well, that's the good part: it doesn't even know about the modules. They are invisible to it, save the startup-output on the console. So, if you don't care about how it works, just grab one of the combined ISOs and boot it! There are different pre-made cd images with a whole range of (currently GUI-centered) software. It has an easy-to-use installer, if you wish to install it to your harddisk, but it doesn't need to be installed. It doesn't touch the rest of your system without specifically asking you.
