I usually have one project I'm focusing on but often have many other projects in the back of my mind for several years.

I would often see windows that looked to me like they weren't real - almost like a painting on a wall instead of a window. I thought it was kind of a cool idea.

I brought several national projects to Katihar.

I love math and was a math teacher for many years, so it was fun for me to write several math books, including 'Fraction Fun,' 'Calculator Riddles,' and 'Shape Up!' 'Fun with Triangles and Other Polygons.'

My work reflects a relationship to the built world that shifts between control and randomness, strangeness and beauty, comfort and fear.

As a photographer, I'm interested in how dramatically photography has changed. Most images are not real or are composites, and most of us don't even know it anymore.
