Anniversary Gift for Jen

This is a small keepsake box for Jen for a simple anniversary gift. The visual equation on top is an inside joke we have shared for almost 30 years now relating to optics and our first year in Physics class at the University of Toledo. The wood is a Brazilian Walnut, exceptionally colorful and dense (just like me sometimes), and it contains some rough fire opals which is apparently a traditional 24-year gift. Not some of my finer work, but it came together in less than an hour.
