Change The Record by Paul Cocksedge
Used vinyl records turned into a simple speaker for iPhones/iPods by heating the record and stretching it over a mold. The final result is a cone which magnifies the sound coming from the speaker. The project was launched at the 2011 London Design Festival, where Paul formed records right on the spot and even asked people to bring their own records. A really great design and DIY process.
