We've been using oscilloscopes in several of our live performances to translate sounds into visuals (thanks to the fine Mr Rob Rainbow, ex Light Surgeons). I particularly like the visual resemblance of the sound waves to threads. For more information about how oscilloscopes work, click on the link above.
Here is one of Yusra's poems created during our first workshop, way back in May 2008, played through the oscilloscope. The left and right audio channels have been combined into a single channel, so it's as though the piece starts with two twisted threads, which depending on Yusra's delivery unravel and re-form throughout the piece.
