Dear Steve, thanks and direct answer to your comment. The craft is a proof of concept that is generic for all sorts of purposes. Later the shape can later be specialized to particular uses: We made some drawings in this. in the presentation that you can download. Your idea intrigues us. Can you make a sketch of it or give a reference. Best, Winfried
