After playing with the cast marble puzzle at Turkeyfest, I ordered one, and it arrived yesterday. It's pretty and a pleasing tactile experience, definitely nice to have on a coffee table or mantelpiece. There are a couple of spots on mine where the marble catches on the frame a bit, but I expect that will loosen up with use. Solving it took a few minutes, but since I was not paying attention when it came apart, putting it back together took significantly longer. Now I have the technique down and I can do it right away, so I have the fun of inflicting it on other people.
Nice work Bram.
