Lighthouse is a series of artworks that uses UV technology to reduce bird collisions with windows. As part of the architecture of the Terracotta Embassy at Jatiwangi, Celyn collaborated with Taiwanese scientist and botanist Hsin-Chieh Hung (plant hunter) to create a new version of ‘Lighthouse’.

Hsin’s research has led him to discover hundreds of new plants, as well as discovering the last remaining specimens of certain species of plants in Taiwan and Southeast Asia. Celyn used the hand drawings Hsin had made of these near-extinct specimens to create the design for this piece, integrating these rare plants into the architecture of the embassy.

Under normal conditions the image is invisible to the human eye and visible only to certain birds, animals, and insects; only under UV light is the design revealed. As well as having a practical function in reducing bird collisions with glass, this artwork series explores the idea of non-human vision, in addition to the relationship we have with ‘hidden’ or easily overlooked aspects of nature.

This series was exhibited at DOCUMENTA 15 in Kassel in 2022.
