What made the nonagons

I believe that light refracted by drops of water caught in the spider’s web you saw last time made the glass elements in my 100mm macro lens produce the nonagonal artifacts that you also saw. What you didn’t see was the drops, so here’s another photograph from the same session at the Crystal Bridges Museum in Bentonville, Arkansas, on June 20. Notice that some of the nonagons in this second photograph are elongated.
