Started with a fairly standard blank of ash, mounted on the lathe and rough-turned to a flat plate form. The main design element here is a Voronoi-style tessellation that I laser-engraved into the surface after flattening the face.
The idea was to cut deep enough that once the voids were filled with resin and the piece was reversed on the lathe, some segments of the pattern would become free-floating but still maintain continuity thanks to the grain alignment.
