This is a picture of the latest mosaic I just completed. It's an Agnus Dei, about 10 inches square. I used a different technique for the gold this time called opus vermiculatum. Literally it means "worm-like work". It is thus called because the tesserae are set in rows following the outline of the image, curving like a worm does. This lends a pleasing natural "flow" to the work as a whole and enhances the central image. So if you notice, the gold tesserae follow the outline of the lamb, flag, and book, all the way to the edge of the piece, instead of being laid in horizontal or vertical rows.
