Awwwwww... you're so mean to tempt me with the idea of a sketch!! ;) So glad you liked that image though. It always makes me smile just a little. Thank you so much for the awesome feedback! I hadn't really noticed how there's only that one quiet spot in the middle - kind of like the eye of a storm. Very interesting was to look at it. Neat! (Sorry for the slow reply - our department's been hosting an academic conference and it's been chaos here!!)
