This is a faceted iteration made by omitting the "tab" step in modo. Keeping with the original goal of this form (see quoted text from first post) a pocket can now be understood as a tool for directing light. "This is an exercise to find a simple component of a diatome that can be aggregated to create non-uniform topography. A tile cupped at one edge can combine with another tile to produce a volume at 0°, 60°, 120° and so on. If a tile is left out a pocket can be formed."
