I'm finding triangles overlapping rectangles are particularly effective.

Not getting the over and under part.
If you look closely the design at #16 is based on an octahedron. There are four-way connections at the front, rear, top and sides. This is what allows the differential prolating.
Also, the triangles can be rendered as diamonds or hexagons. The triangulated shell over a diamond frame would [technically] be triangles over quadrilaterals.
edit: look what I found, A Wellington but instead of showing it's Lamella frame, it's under a canopy that is diamonds over squares.
