Artist Alberto Seveso returns to his colorful ink plumes (1, 2, 3, 4, 5), but this time with a twist. Here, Seveso took ink injected in water and digitally altered it, adding texture and shaping the ink to mimic the shapes of coral reefs. The results are stunning, though I confess a few of them remind me of mushrooms or organs more than reefs. (Image credit: A. Seveso; via Colossal)
