Make a dish based on Voronoi diagrams. Made an Inkscape extension (jim_voronoi.py) that does recursive Voronoi diagrams with optional Lloyd’s relaxation. Seed point layouts can be random or normally distributed from the edge, center, or two or more foci arranged about half way between the center and edge.
Plan is to make a nonogram outline, and do two levels of Voronoi regions. The first level is normally distributed at the edge, the second level is randomly distributed and has one round of Lloyd’s relaxation. Try several layouts, pick one that looks appealing.
Make the main color opaque blue. Cut with a tile saw, clean up on the grinder. Print out the design on two pages, tape together, and match pieces to the design to check while grinding.
Cut a base glass of 3mm transparent, place over the design, glue the tiles in place. Place paper over the glass leaving the main lines uncovered, use Bullseye True Blue Transparent power. Add Glastac glue to fix in place, remove excess, clean up. Mix Glastic Gel glue with powder, add to edge to give a border. Let dry overnight. Clean up some more, use vacuum to remove excess powder.
Mask main lines with blue tape, add Bullseye Aquamarine Blue Transparent powder to fill in secondary lines. Add Glastac glue to fix in place, clean up excess, and let dry. In places, the powder compressed when the glue was added–add more powder of both colors to fill remaining gaps, let dry, clean up. For detail clean up, hold the vacuum close by and scrap off excess powder / glue.
