Interactive light monument for the heroes of resistance.

The monument: LOOM LIGHT is a tribute to Jan Zwartendijk and many other invisible heroes of resistance from the region during the Second World War. The impressive interactive lightwork, marks 75 years of living in freedom.

“The work changes shape and moves with you. During the day, the monument reflects the sunlight. In the evening, a feast of lights is created referring to the Hanukkiah, in which the light is lit by an invisible hand for eight days. It is a tribute to Jan Zwartendijk and the countless invisibles who have engaged to save lives.” – Titia Ex

The work, with a diameter of approximately 3.50 meters, extends from 4.50 meters to almost 6 meters high. The lighting design runs through a parametric model that generates light behavior and 3D printed shells are made of recycled plastics. The sculpture is located on the former NRE energy site in the City of Eindhoven, The Netherlands.


The work is interactive and responds to the approaching visitor. Ex invites the viewer to experience the many meanings she has put into it. The artist transforms this conscious action into a dynamic light motif. With this, Ex indicates how important the acting role (even small) of each individual is, in giving direction to the future.
A light object of her hand appeals to an aesthetic experience of great beauty and is always multiple interpretable.


One of the challenges in the sculpture is the organic non-repetitive horizontal pattern in the 3D print while the vertical pattern had to continue in the different parts to be assembled. This pattern creates an effect of depth that influences the light shades, which evokes a soft, misty atmosphere.

Additional Information

Tribute to Philips director Jan Zwartendijk (1886 - 1976), director of the Philips office in Kaunas, Lithuania in 1939. When the Second World War broke out, the Dutch government in exile appointed Zwartendijk deputy consul in Lithuania. In that capacity, he saved the lives of Jewish refugees in this country by issuing them visas for Curacao in July 1940.
