Boolean logic can be something you hold. These PCB tiles turn selectors, inputs, constants, routes, and intersections into a physical alphabet. Build one choice by hand, then carry it into truth tables, Logisim, FPGA lookup tables, and spatial computing. https://greenforest.io/physical-mux-tiles/
Build Boolean Logic You Can Hold
Circuit role, orientation, topology, and connector geometry become one palm-scale language of fabricated PCB tiles.
