At the season 5 page, you can see last week's "Cover Me" logic maze. The state diagram for the maze is shown below. If you were intrigued by this maze, you'll likely enjoy the Logic Mazes site by Robert Abbott. More recreational mathematics is at the Wolfram Demonstrations Project, which is now supported by Mathematica 7 Home Edition, which was used to create, analyze, and display all parts of the covering maze.
