Shifting water levels in a darkened space are creating an intriguing spectacle reflecting on the world's most precious resource.
Tipping Point is Bristol-based artist Kathy Hinde's newest work, and the installation is being shown for the first time at the Norfolk and Norwich Festival.
Until Sunday visitors to the Undercroft, behind Norwich Market, can explore the work which sees the rise and fall of water in six pairs of glass tubes conduct an ever-changing sound and light show. The audio-visual performance looks at our relationship to water and the effect climate change is having on the water cycle.
'I called it Tipping Point because of the connection with our relationship with the environment and the water resources. 'There's the same amount of water but if one place becomes full another will be empty,' said Kathy.
'I am trying to create a piece where the sound and water levels fluctuate and change, and there's a lot of parallels with that.'
About the mechanics of Tipping Point, Kathy explained: 'There's a mechanical arm alternately lifting each glass tube up.
'The tubes are joined at the bottom to redistribute the water, as one fills up and one empties out that changes the pitch of the sounds.'
A microphone is placed in each tube to capture the sounds which also control the brightness of the lights in the installation.
'It's a meditative exploration of working with water levels, glass and resonance frequency,' said Kathy.
On Sunday afternoon Kathy will present a special performance where she will interact with Tipping Point and 'play' the sound sculpture.
A Cryptic commission for Sonica, Tipping Point is a collaboration with John Rowden at the Scientific Glass Workshop at the University of Bristol with software designed by Matthew Olden.
Kathy has shown her work across the world, including Europe, America, China and Brazil. Following Tipping Point's premiere at the Norfolk and Norwich Festival, Kathy is taking the work to Brighton Festival and then London.
• Tipping Point is at The Undercroft, behind Norwich Market, until Sunday, May 18.
The free installation is open each day from 12pm until 6pm. A performance will take place in the installation at 2pm on Sunday, May 18.
