your local square grid — same rooms, same walls, same facing as the view above, just from overhead. (not the true Penrose tile positions: compass directions are assigned freely during carving, so a "true geometry" map can't agree with what you see in first person — this one always does.) yellow = floor (an open door), red = wall (no door was carved here), arrow = you, facing.

penrose-maze
A maze carved into a real Penrose tiling — the aperiodic pattern that never repeats and can't tile the plane with ordinary 90° corners. Every rhombus tile has exactly four neighbors, so every room you stand in still looks like a plain square.
The floor plan folds on itself in ways a normal building can't. You will never see the seam — walk it, and it always looks locally ordinary. Peek behind the curtain any time with the map button.
