Looking at our Year in terms of light and darkness has revealed a lot of the symmetry that underlies our days, and how we imagine them.
With a recent burst in creative energy, I started making this visual wheels of the year, where each day is shaded from 100% black (the Winter Solstice) through greyscale to 100% white (the Summer Solstice). Because the Winter Solstice takes place at opposite times of year depending on whether you’re in the Northern or Southern Hemisphere, I’ve taken to making 2 of each image.
