The Hummingbird Clock

The Hummingbird Clock is a new kind of public time piece that exists physically as a permanent sculpture and online.
Opposite Liverpool’s law courts, Abu Hamdan's Hummingbird Clock, a tree of binoculars resembling CCTV cameras, keeps watch over the Town Hall’s clock. It is designed as a tool for investigations into civil and human rights violations and state corruption: recording the second by second variations in the buzz made by the electrical grid as a means of counter surveillance. For over 10 years, the UK government has been using this humming sound as a surveillance tool. Nearly all recordings made within earshot of this almost-silent humming can be forensically analysed to determine time and date, and whether the recording has been edited or altered. This technique has, so far, only ever been used by the state, but it can now be accessed by anyone who might need it. If you need to know the exact time an audio or video recorded event took place in the UK after 7 July 2016 please visit www.hummingbirdclock.info

As the secondhand turns around The Hummingbird Clock like a seismograph it draws the line of the UK's fluctuating mains current and this pattern of fluctuation is being recorded and archived every second 24/7.
