I want to say tiling, but that means tessellation to most, and this is not that. Space filling structure? Not really that either.[br][br]Saw this piece from Ghee Beom Kim, reminded me of one of my favorite structures, how each quadrilater dictates a plane filling by similarity.[br]https://www.geogebra.org/m/CUdKaHeC#material/rMgQ7FXM [br][br]For this, I limited myself to kites, defined by the rotation around the chosen center point. I've also got to think about the kite interiors - seems tricky for GGB.
