I realy enjoy this piece, particularly as it makes me aware of how cell phones use energy and how that energy is carried over through the world around us. I am curious though, are the cell phones the only source of power for the entire project? How are you limiting the range of the recptors to the rooms? Also while the lights and feathers serve as indicators of the process and peotic, have you thought about rewoking the piece to do actual work (light the street below, run an air filter, or pwer a fridge for example?

Just a couple of questions
