NOAA provides weather charts for the Atlantic. Every day there’s a new composition, a new layout of the sky. Parts of the map never change: the grid and outlines of land. But what if it were the other way around? Clouds did not move, but the earth did. Every morning, your house, your work, your school, would be in slightly different places. You would consult the daily cloud chart to find your way; navigating by the sky.
