"Threshold" is a play on the threshold as a physical entrance and on the use of the word as a minimum level and, in colour theory, an artifical boundary in a spectrum. The form refers to an archway associated with a sacred space. Being suspended, the form appears more architectural, as well as symbollizing a non-material (spiritual) threshold. Red is also often used to indicate the spiritual in Māori culture.
The Nature-Nurture series are illusionistic works based on photographs of cultivated flowers from a New Plymouth garden in Aotearoa | New Zealand. These are real objects, as shown by the imperfections, arranged artificially and hung out from the wall so that the lighting throws an after image on the wall. This 'seeing through the work' draws attention to the medium, a suspended transparent sheet. It is the equivalent of the words "This is not a pipe" in Magritte's surrealist painting and like his work these are also primarily conceptual works of art.
