"Momentum" was a beautifully documented and executed project by United Visual Artists that was presented at London's Barbican Art Gallery earlier this year. From UVA, "Coinciding with their 10th anniversary, UVA present Momentum, an immersive installation that combines light, sound and movement. Drawing on physics and digital technology, UVA are turning the Curve into a spatial instrument, installing a sequence of pendulum-like elements throughout the 90 metre long gallery to create an evolving composition of light and sound. The pendulums – sometimes moving in unexpected ways – project shadows and planes of light across the 6 metre-high walls and curved floor of the space. Visitors are invited to explore the room at their own pace, and their movement through the gallery shapes their individual experience."
