Spiral Forms

George W. Hart

These are spiral sculptures suggestive of delicate undersea creatures.
I imagine that they swim underwater, propelling themselves forward by a corkscrew motion.
They could maintain their screwing motion by a ripple which moves circularly along the edge.

This one is similar, but with a different pattern to the holes. Both are made of nylon by selective laser sintering.

Both of the above forms nestle inside a sphere, as this side view makes clear.

 A paper describing the mathematical ideas is available here
