steel grass: a shimmering field attuned to the wind
Along the open stretch of Amsterdam’s Flevopark, a cluster of delicate metal forms by collective Aérosculpture rise from the ground in thin, shimmering strips, each catching light as it shifts with the wind. THE kinetic installationtitled Steel Grass, it arrived here for the 2026 edition of the Synergy Art Festival, where its movement is both subtle and steady, a surface that never settles into a fixed shape.
The work relies on the sun to hold its vertical tension, allowing each element to oscillate between weight and lift. What appears rigid from a distance is revealed to be responsive up close. The slightest current passes through the field and sends a ripple across its surface. The movement travels in slow waves, then breaks into smaller tremors, as if the air itself had become visible.

unscripted aérosculpture choreography
Designed by Jean-Pierre David with Aérosculpture collectiveSteel Grass is somewhere between engineering experiment and environmental design. There is no scheduled sequence. The choreography comes from the space, from passing bodies, from temperature and pressure changes passing through the park. A breeze moves across the grass and continues into the sculpture, translating something invisible into a legible pattern.
In brighter light, the polished surfaces scatter the reflections outward, turning each strand into a thin mirror. The field flickers as people walk past it. Sometimes the forms are aligned and the installation is compressed into a dense vertical plane. Then the wind loosens its grip and the threads drift apart again, opening small gaps that reveal the space beyond.
moments of calm
What makes the play linger is the way it handles pauses. When the air settles, movement is drained from the structure and the forms hold their position with amazing precision. The field tightens into a set of vertical lines, each pointing clearly to the sky. The same material that seemed fluid a moment earlier takes on a more intense presence.
This alternation between activity and suspension gives the installation its rhythm. He never asks for a single advantage. Walking around it changes the reading from surface to depth to outline. From an angle it looks like a shiny plane. From the other it breaks into individual elements, each of which follows a slightly different path through the air.

a temporary landscape at the synergy art festival
Synergy Art Festival has leaned towards projects that respond to the environment and participation, and Steel Grass easily fits into that framework. It occupies the park without fixing it in a new order. Visitors pass through, around and past it, sometimes altering its movement without realizing it. A group gathering nearby sends a faint disturbance through the field, a small reminder of how fragile the structure remains.
The installation leaves behind a simple impression. Air has shape. The motion can be read. A field can be drawn using nothing more than tension, elevation, and a light-catching surface. In a park already defined by grass and trees, Steel Grass adds a second layer, one that hovers just above the ground and shifts with every passing stream.
