    "abstract": "This paper demonstrates that the pattern of lipid spiculesthat emerge on the\nsurface of red blood cells in the classic \u0027Discocyte to Echinocyte\u0027 shape\nchange is a generative spiral, and presents a qualitative, fluid- driven\nmechanism for their production, compatible with the work of Douady and Couder.\nImplications for the dynamics of cell growth, plant cell phyllotaxy, programmed\ncell death and gravity sensitivity are explained in terms of a new qualitative\nmodel of cellular fluid dynamics.",
