Out for a bike ride, I noticed this naturally occurring tree diagram.
A few days later, the lovely red leaves were gone.
At the Bridges Math and Art Conference, I was exposed to a wealth of fascinating mathematical and artistic ideas, like these anamorphic images by Jan W. Marcus.
The challenge for the artist is to produce an image on a flat surface that will appear rectangular when viewed on the surface of the cylinder. My mind swirls with thoughts of vector projections and polar coordinates when I view these images.
Not to be outdone, Francesco De Comite created a three-dimensional curved sculpture that projects to a polyhedron on the surface of a sphere!
