Molten Mosaic is a 3D‑printed packing puzzle made up of 19 unique pieces that fit together on top of a black‑and‑red frame. Each piece transitions from a “hat” shape on the top to an “arrow” shape on the bottom.
The design began as an attempt to create a tiling puzzle using 3D pieces that gradually morph from hat to arrow, layer by layer. Craig Kaplan provided the 2D curves that allowed Oskar van Deventer to model this transformation. During the process, Craig noted that the pieces shift position as they morph, meaning every piece ends up different—resulting in a puzzle that is surprisingly challenging to solve.
Molten Mosaic is inspired by the well‑known aperiodic tiling pattern discovered by David Smith and later mathematically proven by Joseph Samuel Myers, Craig S. Kaplan, and Chaim Goodman‑Strauss.
Objective: Fit all 19 pieces into the frame. Designer: Oskar van Deventer
