OK, while technically not a "puzzle", it does market itself as a puzzle. Considered the Holy Grail of toys by some across the pond. I thought Eric might let this one slide...just for fun.

When I first arrived in North Carolina, I worked out of an artists cooperative called Antfarm Studios in the Boylan Heights area of Raleigh. I met Lucas there, and he is a very talented craftsman who works exclusively in the custom blacksmithing field.

Th...
