In studying minimal surfaces I found the nine possible networks of geodesics
on a sphere that contain only 120 degree angles. (The circle is the degenerate
case.) Some have readily available data for their arc lengths but several I
solved with spherical trigonometry. But then I wanted to play with some projections
that I could get from these angle-regular shapes. Incorporating these into a
mobile was suggestive to me of the ways that shadows move. Watching the "shadows"
move is like a projection of a projection.

Statement about my art:

"I like to solve problems with mathematics. Art gives me the perfect excuse
and outlet to do this. Perhaps it's part of the cogitative process to analyze
with numbers. Pages of calculations wouldn't seem to lead to a soft fuzzy picture.
How can I explain it? I see behind art - ratios, formulae, tessellations and
transformations. With computer art those pages of calculations are hidden though
I wish to interact with them. I have embarked on a problem that intrigues me,
that of projective geometry. I'm gathering my tools. My goals are far off with
many diversions between. But I don't worry because the road is more important
than the destination. "
