Property 5: "POSITIVE SPACE is the way that a given centre must draw its strength, in part, from the strength of other centres immediatley adjacent to it in space" (Christopher Alexander). Bactrial growth in a petri dish.
Barnacles. I really like how they look really small and fragile. There is a range of different colours but seem to be a mixture of pale pinks/purples with hints of yellow. There isn't really a pattern except some white lines running throughout. The Barnacles have a circular shape. The texture would be quite rough.
