This unit started a series of many designs that I call Semi-Sonobe. They resemble Sonobe units in many ways, but are folded from half a square rather than from a complete square. Just like with Sonobe, many variants are possible (certainly more than I have designed, and of those only some are published), and many incorporate color changes.
