The name of the soundtrack is "Virus Breathing" I recorded it after narrating the voice over. The track was composed to give a sombre feel to the movie and the mechanical "breathing" in the background is reminiscent of an iron lung like those occupied by polio sufferers who were unable to breathe as a result of the infection. Also, the virus changes its shape slightly in response to changes in its environment, with movement of ions and water across the 2-fold axis of symmetry in a phenomenon known as "virus breathing". Sorry about the voice over, I'm a scientist and not a voice over person, but the narration at least helps to explain what is happening. Thanks.
