The photo below is from an interesting article called “Livinus en het Licht” (Livinus and the Light) which can be found at the Mediamatic.nl website.
The article talks about a restoration and conservation project that will be conducted on the remaining video artworks by Livinus van de Bundt, who was the first artist in the Netherlands to use video techniques to create abstract images. The article says, “His interest in video stemmed from an urge to mold light into a concrete form”.
