Installed on the 15th floor of London’s iconic brutalist landmark, Space House, 372.5~River Thames is a kinetic sculpture that visualises the tidal rhythms of the River Thames. Presented ahead of Earth Day 2025, the piece translates real tidal data into a moving form, using an intricate system of pulleys and counterweights to echo the river’s natural ebb and flow.
Space House, with its panoramic 360-degree views, offers a rare vantage point from which the Thames can be seen meandering through the cityscape. At various moments throughout the day, the sun, and the moon can be seen — reinforcing the celestial forces that influence the tides and reminding us of our planet’s quiet, powerful rhythms.
Filmed over a 24-hour cycle, the sculpture becomes a canvas for light, shifting with the movements of the sun and moon across the sky. As the day progresses, the interaction between natural light and kinetic motion reveals an ever-changing interplay of shadow, form, and texture.
