Some more examples of Patterning patterns.
The Black Square
This simple black square with some coloured lines illustrates a couple of important points.
Firstly this pattern can exhibit a wide variety of variations based on the several randomized parameters it contains. For this reason it's illustrated with two examples here.
(defn rcol []
{:stroke
(rand-nth [
(p-color 127 255 127)
(p-color 255 )
(p-color 200 100 200)
(p-color 200 200 100)
(p-color 102 255 178)
(p-color 255 51 255) ; pink
(p-color 0 204 204)
(p-color 255 51 51)
(p-color 255 255 204 )
])
:stroke-weight 2
}
)
(defn dark-fill [style]
(conj style {:fill (darker-color (:stroke style))})
)
(defn t1
([p] (t1 p (rcol)))
([p s]
(->> p
(stack
(drunk-line 10 0.2 s)
)

(rotate (/ (rand-int 10) 10))
)
)
)

:stroke-weight 2}))
)

(apply stack
(take 3
(iterate t1 (drunk-line 10 0.1 (rcol)))
))

)

Chita
Brazilian floral kitsch "Chita" patterns are common for textiles, table coverings etc. Here's a demonstration of how to approximate the style in Patterning.
