More noteworthy than the technical matter of orientation, per se, is the history of explicitly using south-up map orientation as a political statement, that is, creating south-up oriented maps with the express rationale of reacting to the north-up oriented world maps that have dominated map publication during the modern age.
I always view my maps this way, when on Google maps just swivel the map till the red compass tip points down. Looking at it south up is like looking at a newly generated world in a RPG game.
