I have turned this into an assignment for my students, so I'm letting them come up with the next three designs.
I'm comparing the boulders and conveyors to musical notes on the scale.
I'm comparing Math and Music, using Wonderland as the tool.
I've used the analogy of the boulders/conveyors being to the transporters and filling the water as the paper rolls or cylinders are to the player piano or musical box.
The input determines the output. I have given them strips of paper with four rows and 80 columns. They are determining the most efficient, or coolest, method to fill the water. Each class(3) has a different level design to work on. Unlike "88 Boulders", the paths cross and that creates a different dynamic. They also want these to be levels that you can play. I am more than willing to oblige

I will have the three levels posted later today. I hope...
