This poster is an oversize data visualization of sunrise and sunset times on five latitude lines roughly corresponding to the cities St. Petersberg, Seoul, Shanghai, Nairobi, and Buenos Aires. There is a graph line for each day of the year (it is those lines generating the moire you see on screen). Also shown are the solstices and equinoxes as well as the new and full moons. Daylight savings time was left off because it is implemented differently across countries. The poster has been so popular that a web application is being developed that will generate a graph for any location on Earth.
The poster was mailed to clients of landscape architects SWA Group as a new year’s greeting.
