Implementation of an algorithm
for folding any orthogonal graph/maze together with a
maze puzzle font.
Edit your maze in the top-left, or hit "Random maze", or enter text above.
Crease pattern at the bottom folds into the 3D structure in the top-right.
Printing this page will just print the crease pattern.
Red = mountain, blue = valley (for printed side up),
thin/light = 90° fold, thick/dark = 180° fold.
