Time Out says
Putting a spotlight on the health of the River Thames, artist Jason Bruges’ light installation will shine one of three patterns on to the Sea Containers at Mondrian London based on whether the water quality is good, average or poor according to that day’s Thames data reading. The lights will be a permanent fixture every evening from dusk until midnight, letting us know if the river’s health is improving or declining. The data will also be tweeted on via the @ThamesPulse account and a billboard will show readings on real time. The lights will be switched on for the first on March 16 at 6.30pm.The project was devised by MEC UK to help raise awareness about the condition of the Thames and to support charity Thames21 in its mission to protect London’s rivers.
