Adopts eight patterns in his landscape work, namely: scattered, fracture, mosaic . This in itself might not have appeared particularly exciting, but there was a precedent: stripes and hexagons are exactly what scientists had seen when modelling other instances of pattern formation, for example convection in fluids, or, more strikingly, the emergence of spots and stripes in animal coats. Spots and Stripes tan(sin(x)) < cot(cos(y))-A lot going on, for such a straightforward pattern. An aerial view of an intertidal mussel bed often reveals large scale striped patterns aligned perpendicular to the direction of the tide; dense bands of mussels alternate periodically with near bare sediment.
