Environmental geometry can be described as a form of a-typical psychedelic geometry which differs from standard geometry through the way it is manifested. Instead of being independent from the external environment it is entirely comprised of parts from within the external environment. This results in certain textures such as grass, carpets, asphalt, tree branches and dense vegetation forming into extremely complex geometric structures that are comprised of the original material which they are manifesting from. These structures tend to be primarily symmetrical in nature, but also include form constants, fractals and disorganized geometric patterns.
