Recently I gave myself a little challenge : make a map using a random Coordinates Reference System in QGIS. So I used a random number generator between 1 and 10000, and told myself to make a map using this CRS. It turns out that the EPSG:4938 came out.

This raw and geometric map has basically been made using world countries, negative buffers and re-projected square grid cells.

While making this map, I personally enjoyed using the default yellow color of QGIS's selection, as well as the glitches of QGIS rendering on Antarctica :)
