Originally inspired by the possibilities for speaker design with copper tape, I started thinking about different ways to make this interesting.  My first thought was to make a laser cut enclosure with a magnet in the center, separated by transparent plexi from some sort of conductive material coiled around the outside.  I considered having this either float in a liquid or possibly some kind of light material, such as popcorn or packing peanuts.  I thought it also might be interesting to see what would happen with iron filaments in there as well, whether they would be able to visualize the oscillating magnetic forces involved.  Discussing it with my peers, I was reminded of the capacitive sensing we did earlier in the course and was also referred to this project.  Perhaps it will become some kind of theremin, which could be interesting, but would be challenging to institute an original take on.
