Bathymetric Map Uses Edge Lighting

A bathymetric map is one concerning the floor or bottom of a body of water. It’s the wet equivalent of a topographical map. Made on a Glowforge laser cutter, the design is built of layers of lasercut wood stacked up to represent the natural contours of the bottom of a lake. There’s also a layer of acrylic included, to which special standoffs are fitted. These standoffs hide blue LEDs inside, which allow the acrylic to be edge lit without the LEDs themselves being visible.
