Just saw this on Wikipedia (about the Dymaxion map invented by Buckminster Fuller):
More unusually, the Dymaxion map does not have any "right way up". Fuller argued frequently that in the universe there is no "up" and "down", or "north" and "south": only "in" and "out". Gravitational forces of the stars and planets created "in", meaning 'towards the gravitational center', and "out", meaning "away from the gravitational center". He attributed the north-up-superior/south-down-inferior presentation of most other world maps to cultural bias.
啊,Bucks,不得了。
