Yes, two good tastes that taste great together. Tessellations can be divided into modules, folded separately, and then linked together into a mat. Or, if you prefer, a zero-net-curvature modular. Overlapping one of the tessellation molecules before collapsing gives just about the strongest lock you can imagine. Spontaneously, without further designing.
