Polynesian Wave Maps
I had a studio visitor turn me on to these last week. I find no end to my wonder at how human beings have such capacity for visualizing knowledge that is not visible. These stick charts take the cake for me. Beautiful artifacts of a knowledge that is surely lost today…or at least doubtful to make it through to the next generation.
Take a look at a post at The Nonist that shows some graphics and provides a brief explanation.
