Ah sweet! Nice use of blender; I'm just starting to learn to use it. I'm a long time Ubuntu user, if you need help give a holler. GL on the dist upgrade; I generally stick with LTS unless I get some sort of new/better hardware support in a tweenlease.
Talk to ya later, I'm starcannon on the ubuntuforums.org website, but I haven't been on as much as usual this last week.
