Life is tough and cheerless for Billy Casper, a troubled teenager growing up in the small Yorkshire mining town of Barnsley. Treated as a failure at school, and unhappy at home, Billy discovers a new passion in life when he finds Kes, a kestrel hawk. Billy identifies with her silent strength and she inspires in him the trust and love that nothing else can, discovering through her the passion missing from his life.
Note that this infinite process is not dependent upon the starting shape being a triangle—it is just clearer that way.

The poster of the front of the second banner of the Barnsley Miners Wives Action Group. The artist Andrew Turner was commissioned to paint the banner, based on ideas from the group. The banner was constructed by Sue Turner. One side uses images from the Miners’ Strike and the subsequent fight to stop the pit closure programme. The reverse records the names of the women involved in the group and the local soup kitchens that operated during the strike.
