I try a few times but it seems impossible to take a decent picture and my son, sitting in the carrier on my back, is impatient, I don't have time to fiddle around with the settings. Instead I put down the camera and take a moment to memorize the details. In front of me is a large steel ring, maybe two meters in diameter, suspended in the air between two trees. In the middle of the circle is a trio of LED lights. A series of nozzles all around the ring are spraying a fine mist into the air. As it falls, floating slowly down to the ground, it catches the light from the LEDs, cascades of orange, purple and white that spread out and drift into the darkness. The colorful mists envelop the little grove of trees, creating a fairy-tale-esque atmosphere and you forget for a moment the ring of nozzles and the LEDs.
