21/12/2013. London, UK. A wind powered light display called ‘fLUMENS' illuminates the Middle Dock at Canary Wharf in London on a windy night. 'fLUMENS' was created by Dutch artist Rombout Frieling and Luuk van Laake who is a former wind engineer now working for DigiLuce and aims to visualise the wind. The 'fLUMENS' are solely powered by the wind and have been built to withstand gusts up to gale force 10 on the Beaufort scale.
