The Crawick Multiverse is a conceptual representation of the Universe in the landscape. On the left is the Sun Amphitheatre, the large gassy mounds represent our own galaxy and that of Andromeda, the lumpy bit in front represents a Galactic supercluster (of Galaxies) and the hole with water on the right, not sure, maybe a black hole! I'm sure that thousands of years from now, academics will ponder over its origins.
