|A Really Great Gift
When I retired from Varian Medical Systems, after 41 years, I was given an electron tree (Lichtenberg figure*) as a retirement gift. It is a very special gift that is a fascinating thing to see that some have likened to petrified lightning. The process to make such a tree is technical involving a piece of clear acrylic plastic. My electron tree was made using a piece of 1 inch thick acrylic that is 12 by 12 inches in size. I've always wanted my own electron tree, but never thought I would have one; especially one this big. I felt very honored to have received this gift. The second photo is the most spectacular.
