Labyrinth Folded Corridors Metal Sign

About the Folded Corridors design

An equilateral triangle frames this maze, and every wall inside it runs at one of the same three angles as the outline, so the corridors bend in sharp zigzags and hooked chevrons with no right angle anywhere. At the center sits an empty triangle, a smaller echo of the border pointing the same way. Its base wall overshoots the left corner and carries on into the maze. Near the apex, the passages stack into narrow switchbacks.
