Criss Cross

Tuesday is still Dunkin' Donuts day at the beach for us, even though I don't photograph there each week.  But while sitting in the car enjoying my coffee and donut, I saw this strange pattern of one drift fence seen through another drift fence. It may be what is called a "moire pattern."  "A moiré pattern, in physics is the geometrical design that results when a set of straight or curved lines is superposed onto another set." Anyhow, this was dizzying to look at and I thought it was worth a photograph.  Click on the photograph, it will get larger, and mess with your eyes!
