+The pattern consists of one basic shape – the shape of the leaves. One leave has an organic figure which could be transformed into a geometric form. This geometric shape exists of three equilateral triangles: the first one is the biggest with the hypotenuse at the bottom. The other two triangles are smaller than the first one. They are half sized and arranged in a diagonal way. Two-thirds of those triangles are inside the bigger triangle. Their top shows one to the left and one to the right side.
+The leaves have different sizes which are organized randomly. They are arranged along a line, one to the left and one to the right side by turn. Those lines grow in parallel and even sometimes overlapping. Through this the pattern has an appearance like an organic, random grid which is extendable in all directions.
