The real-time light installation Tessela is currently on view at Perceptual Spaces — Hommage à Vasarely by Light, a group exhibition of the Lighthouse Association and guest artists at m21 Gallery in Pécs (2 July – 23 August 2026), opened during the Zsolnay Light Festival — in the year of Victor Vasarely’s 120th anniversary, in the city where he was born.
Tessela is a homage to Vasarely’s Vega period: a projected, tessellated field that behaves like a membrane rather than a grid. Five generative scenes are rendered live in WebGL2, and the image is never fixed — in the gallery an infrared camera senses the viewer’s presence, and the field bends, breathes and deepens in response. The picture only exists together with the person looking at it.
And now you don’t have to travel to Pécs to look: the web version of the installation is live at tessela.ivo3d.com. All five scenes run in your browser — explore them with your mouse or touch, or enable your webcam and let your movement shape the image, just as it does in the gallery (everything is processed locally, nothing is recorded). Find the hidden menu, and let the field respond to you.
