these are some of the ideas i came up with in terms of connecting the panels together. These can have verying degree of porosity to allow pedestrians/vehicles to see through into the construction. I modeled them as a solid panel, but they can be the frame work in which the panels are inserted. The bottom one is a simple illustration of the sliding system. The panels can obviously be modified to fold down/spin/rotate/etc. The upper left example gives more depth to the panels.
