I have some pictures of Michael Getter's soon-to-open Nantucket restaurant, Dune, and the place looks pretty chill and sandy. They sent one picture in particular, which shows the custom stone bar top. Stone is always cool when it works out, because every piece is unique and has its own shapes and colors. They got pretty excited about this piece for the restaurant, because as soon as they looked at it they saw a pattern in the stone that looked like Nantucket island.
For reference, this is a map of Nantucket:
The bar top is naturally patterned Brazilian quartzite fabricated by GerrityStone.
