You mentioned that Protodermis can be used as a metal foil similar to paper. If that is the case, can the Protodermis foil be used similarly to Chinese lanterns and Aomori Nebuta Matsuri Floats? If so, how would the light pass through the metallic Protodermis foil? Would it be similar to the references I gave you on this current post or would some of the light be bouncing inside the metallic foil?
