Burn the ISO, make a new partition of 10GB or so and leave it raw and install it there or, you can probably run it from CD as a Live CD, this way you're not installing anything on the HD but I couldn't tell if this is possible with this distro, you'll have to try it out. Let us know.
Everything that irritates us about others can lead us to an understanding of ourselves. -- Carl Jung
