  "summary": "A clawed indigo wave unrolls into a snow-capped mountain: foam becomes snow and boats settle into a forest below a mineral-red sun. Woodblock print in motion.",
  "description": "A Japanese-style woodblock print on washi paper with a soft unprinted border. A towering indigo wave with clawed foam fingers, carved contour lines and a few small boats slowly unrolls and reshapes into a snow-capped mountain. The foam becomes snow, the boats settle into a forest, and the mineral-red sun stays where it is. Imperfect pigment transfer and paper grain keep the print feel. It is a one-shot film that ends on the mountain. The film has no settings.",
