Jim, In your discussion for your FOTD for August 26th, 2013: http://www.crosscanpuzzles.com/Aug13/082613.html you say: "...Something in the resulting image reminds me of an undersea scene..." Perhaps it's your fractal's central radiating pattern, that's also found on sea urchins: http://tinyurl.com/Sea-urchins-5-or-15-fold-sym or: http://www.rsc.org/chemistryworld/sites/default/files/upload/sea-urchins_shu tterstock_300.jpg as well their spines -- which are suggested by the sharp green objects in your fractal... - Hal Lane ######################## # hallane@earthlink.net ########################
