The window film I used was made by Frost King and was just clear plastic film that you can get at HD for about $5 per box. It is meant to help insulate windows for winter. I had the idea of trying it to create a membrane like electrostatics and plants. I am always looking for cheap experiments that most anyone can afford. The problem I ran across in the few implementations that I tried with is was the hall effect, or sounding like everything had an echo to it. I haven't experimented as much lately because I am working on a project that uses the panels as a midrange.
No announcement yet.
