Geometry is rarely motionless and is generally extremely fast-moving,<ref name="2C-B"/> and self-changing in regards to its shape and style. During this process, the geometry naturally drifts laterally or radially across the visual field to create overlapping webs of geometric patterns which transition through many distinct states, all of which are visible within a single perceptual frame.

This experience is often accompanied by other coinciding effects such as [[internal hallucinations]],<ref name="Juszczak2013"/> [[environmental patterning]], and [[drifting]]. It is most commonly induced under the influence of [[dosage#common|moderate]] [[dosage|dosages]] of [[psychedelic]] compounds such as [[LSD]],<ref name="Juszczak2013"/> [[psilocybin]], and [[mescaline]].<ref name="Bressloff">Bressloff, P.

This effect is capable of manifesting itself across known nine different levels of intensity, these tend to depend on the dosage, but can also fluctuate wildly in their intensity due to external triggers such as a person's [[set and setting]]. The individual levels are defined below:
