Ursa_minor I want to see the blueprint for one of these.
Big Beef Burritos Supreme It's core is an armature linking the center pieces of each side to a central hub that allows rotation. The faces are made of interlocking sliding tiles with special pieces at the corners and sides.
This puzzle has a much higher count of unique pieces than the cubes, which regardless of the number of tiles can use the same part for the majority. I imagine it was a long and precise task to produce this. Autism ahoy!
