Jason Bruges‘ new installation “Litmus” – Havering Roundabouts Project are four interactive sculptures located on roundabouts along highway in Essex (UK).

The sculptures are covered with an array of LED pixels. Each one acts as a giant litmus paper, sensing and responding to environmental stimuli, such as daylight, wind and tides in this riverside area.

They measure and display the light levels and tide levels at Tilbury. The latter is particularly important for the Royal Society for the Protection of Birds, who monitor birds on the marshes. A further two towers are located where the traffic turns off the A13 into the Rainham area. The southern ‘Litmus’ tower displays the power generated by the neighbouring wind turbine while the northern tower counts and displays the amount of traffic entering into the Rainham area.
