“Probably the top predator would have been a cephalopod,” likely an ancestral relative of today’s chambered nautilus, with its intricate spiral shell.

At the core of the house is an oak stairway resembling the interior of a chambered nautilus that links all three floors.

Like a tiny submarine, the chambered nautilus speeds through the ocean on little jets that it creates by sucking in water and spitting it out.

Spirals like the ones found within the chambered nautilus form a shape known as a logarithmic spiral, in which the gaps between each whorl are spaced incrementally farther apart in a precise mathematical manner.

In one of the smaller eastern windows stands a chambered nautilus that was a gift from my friend Kyle Gann, the composer and musicologist.
