For GLOW 2019, we combined our strengths again and created Hypar: a challenging shaped sculpture in the shape of a hyperbolic paraboloid, introduced by architect Heinrich Engel in 1967. This interesting installation has a focus on the visitor-sculpture interaction, something that is quite unique at light festivals. Hypar connects individuals with different backgrounds, cultures and expertise areas and lets everyone be a part of the creation of the highlight of the installation: a beautiful light show.
