This is a visual maze generator using Python generators.
The current version maybe a nice example
of how to use the yield keyword for a co-routine.
The original code was written in 2010,
at the Libre Grapics Meeting Brussels
auditoriun, much earlier than the
introduction of special syntax
for co-routines in Python 3.5
The current code uses Pygame as a graphics-backend, the project revival in 2019 aim to add a text backend using the "terminedia" library.
