Maze is a four letter word.
I have always had a fascination with mazes. When I was in fourth grade, I would create mazes with my friends and we would solve them. As I learned to program computers, I would create programs that could solve a maze (by brute force). Every so often I will find a new medium I can use to create a maze, and I'll try to make it in that medium. There is a certain art to a good maze - it has to be visually appealing overall, be challenging, but not too intimidating that people will give up.
That said, I have encountered too many problems whose solutions appear to be a twisty maze. That are not as visually appealing or artistic.
