Echinodermania
Polyhedral Forms
These are imagined undersea creatures
based on the {5,4,5,4} hyperbolic
tessellation. The example above has a dodecahedral form.
This computer rendering shows some of my intended details that
were too small to fabricate.
The above example has an icosahedral form. Compared to the computer
model below,
you can see that the intended fine peripheral details were too small to
reproduce.
Each is about 4 inches in diameter and
made of nylon by selective laser
sintering.
I colored them to help show aspects of their form, but they are
difficult to understand from images.
There is a paper describing the
mathematics
here.
