Nocturnal Interaction
At night, a variety of other creatures emerge, including interactive tubeworms, musical drum crystals, luminescent wall crystals, and a misting pond with glowing grass. The tubeworms sense the nearby proximity of people through a capacitive sensor, causing them to react musically, optically and mechanically by retracting into their shells. The drum crystals allow a participant to create rhythm sequences synchronized with the glowing wall theme based on how hard they are tapped. Movie shows the audience interacting with the drum crystals and the fiber optic tube worms.
