I just saw the 28c3 talk, kudos for the work you've already done at Stuggart! As far as my background is concerned, I studied physics at the university and am currently doing a phd in planetology. My main skills are therefore in physics and programming / numerical simulations. Just trying to get familiar with the project at the moment and I will hopefully find how to contribute soon! In the meantime, I'm already training my computer to share its idle cycles for constellation :p
