Figure 18.

(a) Strips of panels cut out from flat sheets can be used to construct the three-dimensional, non-developable tube. Dashed lines indicate fold lines, and the tabs at the sides of the sheets can be used to attach sheets together. (b) Physical model of a six-sided polygonal tube that forms a star when fully deployed. (c) Physical model of the reconfigurable origami from figure 1 is shown in different configurations. The tabs for attachment are visible on the bottom. (Online version in colour.)
