Cerrynt

Interactive projection (2026)

Cerrynt [kerint] means flow or path in Welsh.

The installation is based on the principle of collective drawing, whose visual stream is guided by a generative algorithm.

It transforms input from visitors' smartphones into a fluid dialogue of shapes, traces, and messages.

An open space for shared imagination emerges, where individual gestures merge into an endless, ever-changing stream of images.
