Presentation by Lise Autogena and Josh Portway 7.30 pm at the Terraces Bar and Grill, Madeira Drive, Brighton (near the Sea Life Centre).

Lise Autogena and Josh Portway talked about their work, including two arts-science projects. Black Shoals is a simulation of the stock market as an A-Life planetarium that premiered at Tate Britain and is currently on touring Europe. Acoustic mirrors is an exploration of little-known historical technology: concrete dishes and curved walls known as Listening Ears which were used as experimental listening devices to give advance warning of enemy aircraft. The best known examples are at Lade, on the south coast of England near Folkestone. They were used from 1915 onward, with some success, but in WW2 were rapidly made obsolete by radar. Autogena's is currently building two new mirrors - one in Folkestone, the other 25 miles away at Wimereux in France - for listening to the sea and, ideally, communicating between the two stations by voice.
