Simon Heijdens’ Shade installation at Now Gallery London showcases a responsive glass facade reacts to wind passing overs its surface, scattering triangular patterns of light and shadow in. The effect of the installation is created using sheets of responsive film fixed to glass panels.

The film on the glass responds to fluctuations in the wind outside, changing the tessellated triangular sections from clear to opaque in ripples as gusts flow across the surface. As the sun moves around the facade and varies in intensity, the patterns gradually shift around the interior. The inverse occurs at night, when the light inside is projected in patterns onto the pavement surrounding the exterior.
