Recursion

Album art by Leif Podhajsky for Innerspeaker by Tame Impala. This image serves as an accurate replication of visual recursion manifesting over a natural landscape.

Recursion is defined as a visual distortion which partially to completely alters the appearance of one's external environment by repeating specific sections of itself across itself in a self-similar fashion. It results in the appearance of fractal-like patterns which often zoom into or away from the original image. This effect typically occurs spontaneously and rarely sustains itself for more than several seconds.

Recursion is most commonly induced under the influence of moderate dosages of psychedelic compounds, such as LSD, psilocybin, and mescaline.
