Volvox barberi is a multicellular green alga forming spherical colonies of 10,000-50,000 differentiated somatic and germ cells. We observed that in culture, these actively self-organized just few minutes into flocks contained as many 100 moving rotating collectively for hours. The formed two-dimensional, irregular, active crystals, is, geometric lattices within which individual rotated separate...
