Photography from the show,
by Pino Dell'Aquila

A knot carven in hard-rock maple.

This piece of the discriminant for real binary quartic forms would show its true symmetry if I could carve it in four dimensions.

A portrait of the artist as a young man.
That coat is now twice as old as my students.

The front of the flier

This brass piece (an early effort in casting) was about two inches long: I wore it around my neck until it was lost, some years later.
It startled me to see it so much larger in the photograph.

The back of the flier

traduttore, traditore!
