Just checking in on the vintage goods at the awesome Landscape Products in Tokyo, and what do I find? A little kit for a Herman Miller kite. It seems to date from around 1980.
The triangular pieces covered with HM logos fit together into a 4-tetrahedron tetrahedron. Not sure what you call that, geometrically speaking, but the Peter Pearce, the engineer who patented it, sold it as a Tetrakite.
Hmm, Pearce also created the Synestructics construction toy system, sort of a Tinker Toy for the Buckminster Fuller generation. And if that's not enough, he worked with Eames and built the Biosphere 2. And this thing, a walk-in replica of a diamond molecule.
