Several themes run though the work:
- Shetland Lines is about lines in the landscape, both large and small scale.
- Death at Decca documents decay and destruction around an old wireless navigation station in Shetland.
- The Window on the World series views the world through narrow slots
- The EnvironMENTAL series comments on waste and destruction in the landscape.
- Onset of Rain gives the alternative (and more familiar to Shetlanders) view of the island.
