Purl is a participatory sculpture, its expanding form able to be constructed in and outdoors, responding to the shape of the site it occupies. Visitors write, draw, make marks on strips of soft yet resilient paper-like material, connecting them to form a sculpture that grows into a honeycomb web, weaving thoughts and memories, telling a story, sending a message, making a wish, expressing a desire. A particular theme to inspire participation might impose itself from the outset or emerge over time. The sculpture can be appreciated and experienced at every stage of its evolution, in the way that it becomes over a period of time, the way the individual elements link to form a larger whole, where their meaning shifts as they join other lines. The sculpture emerges, a subtle performance, an intimate shared experience.
