Nautilus Fountain 1 

I have always liked the Nautilus shape. The "Spira mirabilis" and logarithmic spiral as described by Descartes and often found in nature.

When we were completing Villa Madonna on the beach, the owner asked what I was going to do under an exposed staircase on the loggia (see before image). It is in my pocket, I said. (I knew the question was coming and had sketched it a few minutes earlier with a ball pen and literally had it in the back pocket of the bermuda shorts).
