Petalfold · Hidden Faces
Open hidden pockets in an eighteen-triangle paper ring. Pinch, reverse pinch, rotate the working hinge and turn over to reveal six secret faces. Eight short paired-face puzzles with exact shortest-route nudges, unlimited undo, leaf-number diagrams, an unfolded-strip view and a device-local collection journal; open-ended free play. Original Flexagonator hexahexaflexagon leaf-tree transformations and Canvas geometry renderer retained unchanged, with a new guided interface. A discrete paper model, not a physical folding simulation.
