Batrachospermum is a series of graphics embroidered in fabric inspired by a macroinvertebrate family of freshwater red algae with beaded appearance, varying from blue-green, olive, violet, gray to brownish. It contains a uniaxial central axis with large cylindrical cells; four to six pericentral cells produce repeatedly branched fascicles of limited growth. I discovered these little creatures looking at a science book at home and I was amazed by the beauty of the shapes as well as the function they have in ecosystems and the almost mathematical rules that define their bodies.
