'ryvita mat' was a rectangle area of ryvita biscuits laid at the entrance to my studio. People had to choose whether to jump over the ryvita mat or walk across it. When it was walked across you could hear it breaking under foot. Most people walked cautiously but some people relished the feeling of being destructive. At the point of the photograph above it had reached a fragile and somehow beautiful phase at which people seemed most reluctant to disrupt it. Eventually the ryvita mat deteriorated to the point where nobody cared and it was simply debris on the floor.
