The Gyrograph project explores the visualisation of physical forces through photographic process. Constructed from the hub of a discarded bicycle wheel, the apparatus functions as a motorised rotational instrument. Through a system of gears, pulleys and mechanical adjustments, the device allows controlled variations in rotational speed and axis.

Within a darkroom, points of light are mounted across the spinning structure while the camera records a single long exposure. As the wheel accelerates, centrifugal force produces a spectrum of velocities across its radius. Lights near the outer edge move at greater speeds, producing elongated trajectories, while lights nearer the centre describe slower, more complex and erratic paths. The resulting patterns appear both chaotic and ordered, echoing the precarious equilibrium inherent in a moving bicycle, or perhaps life itself.

These images often evoke astronomical phenomena – nebulae, orbital paths and stellar formations – suggesting parallels between mechanical motion and the larger dynamics of the universe. The Gyrographs therefore function as visual records of invisible forces; gravity, inertia, energy and time, all drawn into tangible sculptural form with pure light.

The title of each work is derived from the hexadecimal value of the central pixel within the image. This seemingly technical nomenclature references the digital architecture of the photograph while highlighting the tension between randomness and order. While two images might theoretically share the same title, the physical conditions that generate each exposure ensure that every Gyrograph remains entirely unique.

Printed directly onto aluminium dibond, the metallic substrate amplifies the luminous structures within the image, transforming captured light into delicate filigree patterns that appear almost electrically charged.

Situated between scientific analysis and artistic exploration, Gyrographs invite viewers to contemplate the hidden forces that shape both the microscopic and cosmic worlds.
