Box with Decorative Mazes
Here is a box and two lids decorated with mazes.
Joe Wingbermuehle has written maze generators in many languages - http://joewing.net/projects/maze/ -; a nice project worth a look. The program in fortran, maze.f90, is easily converted to make input for openSCAD's surface command.
Output from maze.f90 and openSCAD code for the box and lids are included.
