The photographer duo who took this image ask: "Is it molten lava from an erupting volcano or a tie-die pattern from a 1960’s T-shirt?"

It's a variegated water lily leaf floating on a lily pond at the Mission San Juan de Capistrano in San Juan Capistrano, California.
"The water lily family, Nymphaeaceae, is an ancient family with remains having been found in European pre-Ice Age stratas," explain the photographers, Linda and Dr. Dick Buscher. "Europeans first discovered the beautiful plants in the deep, wide lagoons of South American jungles early in the last century. Water lilies have now spread around the world, adding beauty to both natural and man-made ponds."
