My latest creation is a good example of what happens when a builder gets carried away with a simple concept. My simple concept was to use blue bubble domes as microcolonies, which grew into a large mass that I am calling The Death Ring (see story on Flickr).
The large dome is constructed from stretcher hoses that maintain the shape without central supports. The smaller domes contain glow-in-the-dark disks that give off an eerie light in the dark to simulate the glow of the bioluminescent spheres in space. The size of the model may look deceptive due to all the small greebly bits that play with your sense of scale, but the actual diameter is 1.5 feet.
