A form of steganography in which an 'innocent' picture encodes a message.

The graph of the above maze is: 
 /-\ i
A - a | / \
 \-/ g h
 \ /
 f
1-\ /-3-\ |
| >S< >-c-d-B
2-/ \-4-/ |
 e
 / \
 f---g

Although the message may not be easily understood, this is one of
many ways to encode information into a maze.
