Tactile, three-dimensional maps of coastlines were carved out of wood as long as three hundred years ago. These Inuit charts are usually carved from driftwood and are meant to be felt, rather than looked at. Usually the actual landmass has been highly abstracted — it is the edges that can be ‘fingered’ on a dark nigh in a kayak. [And unlike an iphone] it will float if accidentally dropped over-board. - Vitor Papeneck
Important to remember is that these are maps of place, not space.
