My first solo exhibition of mathematical art was mounted at Carleton College, a year after I visited there as Benedict Distinguised Visiting Professor. That exhibition traveled to the University of Minnesota, Twin Cities and the University of St. Thomas.
In early 2016, Bob Stricharz of Cornell University surprised me with a kind invitation to bring a show to Cornell during my 2016 sabbatical. That was the year for art shows, because Bill Barker at Bowdoin set up a show for me as part of a grant called SymmetryWorks! I have been delighted by additional invitations to create variations on a show called SymmetryScapes. Sewanee, the University of the South; Pacific University; Cornell College; and Temple University have all worked with me to present exhibitions
The catalog from SymmetryScapes West, at Pacific University will give you an idea of what visitors were able to see and read as they walked through the exhibition.
For all these shows, I allowed the institutions to print the work without paying royalties and keep the works to display in their departments. A reasonable honorarium and travel expenses for a public lecture associated with the exhibition have been the only expenses for me to put in an appearance. And I am developing new work all the time.
My thinking is that, while others need to earn a living from their mathematical art, I have a regular job that allows me to do this work. So far, I have not felt the need to monetize my work. I just want to share the joy I have found in this work.
