Header Design

Anyone know what that is up there?  Melissa suggested that my granddaughter Kelsey make a circle inversion fractal for her calculus project for pi day (3-14).  Of course I had no idea what that was and never took calculus since it wasn't offered in my school.  I do know about pi because I did have four years of math in high school.  At our school that involved Algebra I and II, Plane Geometry, Solid Geometry and Trigonometry (semester of each).  I had a slide rule and knew how to use it!  Actually, I had two of them a regular rectangular one and a round one.  Anyway, I googled "circle inversion fractal" and thought they were pretty.  So now I have one on the header of my blog whatever they are.  I'm not willing to try to learn that math.  

Here are some others.  Some of them look like jewelry, a kaleidoscope, or other pretty designs.  Who knew math is involved?  Well, Melissa.  She's incredibly intelligent and reads physics books for pleasure.  It's amazing how much stuff she knows.  

I just read Mrs. Miss A's blog and noticed that she knows about fractals.  Shout out to you, MMA!
