Ooooo goodie!(said like a little school girl)

I've fond of spaceship designs that look biological sort of. This is quite rational to. Biological systems have had millions of years of natural selection work on them to produce structures that have maximum surface area for a small volume and vice versa. Curved shapes are better. More stuff can fit inside a ball that is build using less material than a cube.

A ship that looks like a cluster of grapes.
One that looks like a stack of M&Ms one on top of the other.
Various cones that taper at varying spots down the length.
A large torus with small spheres here and there on it.
A large sphere with a much smaller one attached by a few small contact tubes.
One that looks like a mushroom that has a sphere on the other end of the stalk from the large cap.
And other stuff that is much to hard to describe. I'd need to draw them.
