How is it made? Starting with a bathymetric chart (the underwater equivalent of a topographic map), laser-cutters are used to carve the contours into sheets of Baltic birch, then they are glued
together to create a powerful visual depth. Select layers are hand stained a blue-green so it's easy to discern land from water, major byways are etched into the land, then a custom, solid wood frame with a sheet of
durable, ultra-transparent acrylic is added for protection.
