The magical wonders of Norrköping Light Festival! Is this the dragon from GoT or is it Smaug from The Hobbit? It's "Rotifers" by the American light artist Nicole Banowetz. Rotifers are microscopic or near-microscopic animals, 0.1–0.5 mm long common in freshwater environments with a few saltwater species. Rotifers are an important part of the freshwater zooplankton, being a major food source and with many species also contributing to the decomposition of soil organic matter.
