I created the Biosphere as a 3D/social experiment. I started with no planning and began posting my progress up on BlenderArtists forum to see what other artists thought it would become. When I started I had no idea where it would end up or what it would become. As the project evolved I decided that I would release the final result as a free 3D file to the community.
Check the images above for my progression and the link to the .blend file is below.
