#Projections for #30DayMapChallenege

An animation of 24 hours (from midnight at UTC+00:00) on Earth today, in four different projections: Left to right, top to bottom: #Orthographic, #Stereographic, Interrupted Goode Homolosine and #Spilhaus.

Plotted with #cartopy 's Nightshade function (repeated calls to get the different twilight zones) and #matplotlib at 15 minute time steps and then stacked together in #gimp

Background image is cartopy's `stock_img()`.

re-used some code I threw together recently to make a thing for changing my desktop background: https://tlohde.com/blog/2025/10/because-i-cant-afford-a-geochron/
