Prankster artist Mark Jenkins, infamous for distributing "tape babies" around Washington DC and transforming parking meters into lollipops, made a video demonstrating how he casts a head from packing tape. Jenkins tells me that this is the process by which the tape men in his installations are "fabricated/cloned." I don't advise anyone to try this. In fact, it seems like a great way to suffocate yourself and die if you don't do it properly.
