Phosphenic Languages
This work explores an experience where our sensory understandings and the physical properties of waves intersect.
Phosphenes, a neurobiological occurrence of perceiving light in the absence of actual light, exist alongside Cymatics, the revelation of shapes through the interplay of vibration and matter. This work explores the intersections between the two phenomena, creating a visual coexistence through fluidity, dynamics, light and language.
Within analysing the visually similar forms of Phosphenes and Cymatics, the artist explores the relationship between human perception and the external world, as well as the broader dialogue between art and science.

Research
Hans Jenny was a renowned Swiss physician and natural scientist of the 20th century who left an imprint on Cymatics; a field investigating how sound waves interact with diverse materials. Expanding on Ernst Chladni's foundational work, Jenny coined the term "Cymatics", a conclusive word describing the study of sound and vibration.

In the 19th century, Hermann von Helmholtz, a German physicist and physician, became deeply intrigued by phosphenes. From this intrigue, Helmholtz conducted many experiments. He was dedicated to recording his personal encounters through intricate drawings. These illustrations, representing his firsthand experiences with phosphenes, offered an insight into the subjective personal nature of phosphenes.
