Here kids are walking over a lighted floor that forms Voronoi regions of all points closer to one child than to any others.
Here are two visitors riding square-wheeled tricycles in circles on a catenary floor. A catenary is the curve of a hanging chain. Inverted, this curve forms the bumps on the floor that smoothly match with the rotating square wheels. It is quite a ride!
Even the restroom sinks have math connections.
Alas, the sole probability and statistics exhibit was a Galton board or quincunx, that was out of service.
This model has a lever to change the positioning of the pegs that direct the travel of the balls to the bottom. The lever is shifted to allow for non-fair (non-50-50) directions of the ball drop. The left-shifted pile of balls at the bottom suggest, that before it stopped working, the lever was set for the balls to fall to the left with a greater probability than to the right. This is much like a device that Karl Pearson, Galton's protégé, illustrated and wrote about in 1895 showing many individually sliding rows of pegs to vary the probabilities of fall to the left and right.
