A Triangular Domino with another (incomplete) set of pieces.
The inner set of pieces results in a puzzle equivalent to the Triangular Domino. The outer set consists of three pair of pieces. The puzzle therefore looks as if one fused a Triangular Domino with a Grimace, although the Grimace was unknown by the time this puzzle was presented.
This puzzle is a collaboration between Nikola Tutic and Frank Schwartz. Nikola designed the puzzle. Frank duplicated the 3D-printed masters by casting, assembled and stickered the puzzle.
