I'm a passenger on a road trip today, so I've been reading news and stuff on my phone. I read this article: http://www.popsci.com/bae-wants-to-grow ... -on-demand
And it reminded me of one of the methods of organic hull that I've thought about. Organic hulls (and technologies) are one of those things I've thought about doing someday.
1. Organic materials grown or 3D printed into otherwise recognizeable technologies and hulls from the standard tech tree. Obviously this is going to be the way inorganic hulls and techs will be done. The difference being that perhaps organic hulls and techs will require different resources and perhaps pick up organic traits like self-repairing, photosynthetic energy production, etc.
But honestly speaking, this type and standard inorganic hulls and technologies would probably just be treated the same in the rules.
2. Organic creatures as vessels. These are creatures that maybe have some inherent tech-like abilities, but also have technologies installed into them like inorganic hulls.
3. Organic creatures. This was the one that really fascinated me. Instead of technological advancement, I considered a tree of evolution instead. Systems would be like organs in the creature and off-spring could advance the evolution of better abilities with chances of new evolutionary offshoots. Brings a whole new meaning to Trees and Branches!
So what do ya'll think? Can anyone think of other possibilities? Other ideas related the above? Or do you just hate the idea altogether?
