Here's something I did ages ago. It's a way of doing non-simply connected
mazes on an ASCII screen. It takes a bit of getting used to, but you can
make a pretty difficult maze fit in a screen.
Rule: go from the arrow-head of your choice to the first arrow-tail
that points in the same direction.

The shortest path has been marked with + instead of -
and I instead of |.
