The scene is viewed from above: Eight women in white halter bathing suits and matching swim caps form geometric shapes in a pristine turquoise swimming pool. They cascade like dominoes on the diagonal, join their arms and legs in kaleidoscopic compositions, and peek out from under the white shimmery discs of open parasols.
