The Abyss Table by Duffy London
This mesmerizing table was first conceived by Christopher Duffy — and ultimately refined by the team at Duffy London — to represent a 3D geological map of an ocean floor. The Abyss Table makes use of contour lines, which are often used to denote topography in terrain maps, to render an island chain and ocean abyss.
Contour lines can be thought of as workaround for the 2D limitations of paper maps, but Duffy instead relished these simplifications which have become iconic imagery for the field of cartography. He incorporates layers of wood to represent the land, and panes of glass for the water, in order to produce a 3 dimensional geographical model.
