I have a family friend who works at Scripps Institution of Oceanography and he had 2 different bathymetric maps of La Jolla Shores (one from the 1960s). I made 2D and 3D versions. 3D version was a lot of work to trace the image, make the layers and then cut it out.

This was my rough draft/proof of concept, I plan to use nicer wood and make a box for it:
