»Sousaphonograph«, (2005) Original four-valve Sousaphone mounted onto a delicate clockwork phonograph mechanism designed to play a 78 rpm recording of “The Stars and Stripes Forever” through the hon while the turntable and the horn rotate around the playing record, completing one exact revolution for every two sides played. By Paul Etienne Lincoln.

“Hornmassive” is a 2-ton mobile 2000-watt steel and aluminium horn sound system. It is powered by a commercial 12 inch speaker driver and it functions as a mobile audio input station that one can use to project “content” a distance of 1 km. By Matt Hope.

FM Radio Map. This map plots the location of FM commercial and pirate radio stations within London. The poster works in its own right as a piece of information design, but when connected to the modified radio it becomes part of the interface. Placing a metal contact onto each point enables us to listen to the sound broadcast live from that location. By Simon Elvins.
