This month's challenge was all about the unusual - taking familiar concepts and turning them on their head. Here's the challenge brief:

This could be a map of a landmass the shape of the Mediterranean with the sea of Europe to the north, and the ocean of Africa to the south. It could be map of the dwellings of the earthgliding Xorn that live and move in solid rock, but cannot travel through the open spaces of the dungeon. It could simply be a map of the world where north points to the bottom of the page.

For this challenge - think about what familiar conventions we rely on in maps and mapmaking. Pick one of them and turn it on its head and see what results. Don't be afraid to experiment and try a few things before settling on your map - this is an exercise in challenging the viewers assumptions (and your own).
