TESSERAE

A mosaicist with no plan sets this mosaic one tessera at a time. Each stone goes along the nearest guide line, called the andamento, which is the contour of the 0-sphere's field. Each stone sits next to the last one, turned to follow the line and cut short where it would overlap. The six charges of the 0-sphere sit at the centre: 2 dots (0), 2 vectors (−1) and 2 edges (+1). Their field shapes the flowing rows. Tap anywhere to move the 0-sphere and set a new andamento.

LIT: opus vermiculatum is the Roman technique of laying small tesserae in rows that follow outlines. ANALOGY: the guide lines are the equipotentials of six point charges, and the stone colours are drawn from the eight q.d hues and electrum (79/21 gold to silver). Self-check: the 0-sphere's charges must sum to 0.
