Environmental patterning is the experience of certain textures or objects such as carpets, clouds, and dense vegetation drifting into increasingly complex geometric patterns that are always clearly 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 disorganised geometric patterns.
Environmental patterning is often accompanied by other coinciding effects such as symmetrical texture repetition, geometry, and drifting. It is most commonly induced under the influence of moderate dosages of psychedelic compounds, such as LSD, psilocybin, and mescaline.
