Threepenny Shadow
Abysses is a dual‑screen installation where small hand‑sculpted plastic mobiles generate two parallel image‑worlds. On one side, a hard spotlight expands the mobiles into large, atmospheric shadow‑landscapes. On the other, a camera and custom real‑time software transform a similar mobile into a symmetrical, pulsating digital organism. The viewer walks between these two ecologies—one growing outward like an environment, the other folding inward like a lifeform—entering the perceptual gap where matter splits into diverging realities.

Pre‑Abysses Video Works
These earlier video works explore how simple materials, light, and digital processing generate unstable, multi‑layered images. Through the ombroscope and software‑treated footage, forms split, merge, and reappear like perceptual tests—inviting multiple interpretations within a single frame. This body of work establishes the visual and psychological foundations from which Abysses emerges.
L’Ombroscope
The Ombroscope is a low‑tech, early‑cinema‑inspired device that explores how light and simple materials can create unstable, psychologically charged images. This experimental setup laid the groundwork for the perceptual logic developed in Abysses.
Psychedelic Vivaldi
Psychedelic Vivaldi is a prototype for the Abysses installation, built from projectable sculptures animated through a custom real‑time software. The system transforms these physical forms into hyper‑saturated, constantly shifting images where colors pulse, fracture, and recombine. This psychedelic visual field tests how a simple object can generate multiple perceptual readings—an early exploration of the optical dynamics that later unfold in Abysses.
