Long before silicon learned to think, humans encoded logic into cardboard and geometry. A designer known as Akrasno has revived that tradition with the XXO-Master — a 3D-printed mechanical computer that plays Tic-Tac-Toe without a single electron, using edge-notched cards and gravity to guarantee it will never lose. It is a quiet reminder that intelligence is not a property of electricity, but of structure meeting circumstance.
