Today we looked into other alternatives for moving the string attached to the pendulum. We thought about using a motor and an Arduino to move the string with the waves of a song , but this seems extremely difficult to pull off. We also couldn't find anything online where people have done this before. We think we're going to make the arm that the string attaches to move horizontally to add another layer of process. We also came up with the idea to use a lower powered laser to activate thermocromatic (heat sensititve) paper. We will look into prototyping these ideas tomorrow.
