When dusk turns to night and the sky becomes as dark as the sea, a girl imagines the sky and sea merging into one, the lights from the distant ships morphing into stars as she stands on a cliff before the yawning depths of the cosmos. Out from her reverie, spacesea is born - a shimmering shoal of fish become the Milky Way, stars are biolumiscent jellyfish, balls of coral orbit as asteroids, baby octopi transform into shooting stars, and pods of blue whales sing the gentle song of the cosmos.
