Zack Treisman and I first thought of this object when we were working
on our "Demonstrations" book at University of British Columbia
where I gave a colloquium talk in late 2008. It always surprises me how
such a simple construction can give rise to such a biomorphic shape.
It was fun working in Zack's office tucked away in the Math building and
surrounded with old worn wooden furniture. We took a break and went for
a walk down to a beach strewn with driftwood.
Then in the summer of 2010 when Zack came to visit us in Miami, we decided
to make it out of stainless steel and cover it with some latex sheeting
that I had gotten in the meantime.
