My very good friend and fellow metagrobologist, Dave Holt, sent me this puzzle as a gift totally out of the blue. It is the Melting block packing puzzle designed by Tom O'Beirne. It is one of the few 3D packing puzzles that I have actually been able to solve and is VERY clever. I wrote about it nearly 3 years ago in this blog post. My original version was made by the Pelikan workshop in Maple and Padauk.
My new one is VERY special because A. it's a gift, and B. it's made of lots of gorgeous woods:
Ash, Walnut, Mahogany, Purple heart, Wenge, Pau Amarillo (Yellow heart), Beach, Elm, Cherry and a Mahogany box.
