And now a programme that poses the question – where does sound go? If sound can make impressions in tin foil or a wax cylinder, then why not in a wall, however infinitesimal that may be? And what would happen if someone made an apparatus that could extract these sounds from say, a wall? Well the result might sound a bit like this.

This programme won 2nd Prize at the BEA Awards, Las Vegas 2008
