“…Periodic, symmetrical tessellations have been considered as a way to foreground tile boundaries (Akleman et al 2000;Serrentino 1999;Breen et al 2007), but not as much as a system to define the tile as influencing the method of tessellation. Other methods explored digital algorithms such as cellular automata (Bitonti 2009) to create tiles that operate as a set of active, varying figures, but stay within a prefixed tessellated grid.…”
