This animated map of Earth shows the changes in Arctic sea ice and vegetation throughout the seasons. Each frame in the GIF shows one month out of the year. The map is made using open data from NASA, USGS, and Natural Earth. I've open-sourced all the code here in a tutorial that explains how to recreate the design. If you'd like, you can also buy a poster of these maps for the Earth, Moon, Mars, Mercury, and Venus.
