I struggle in life to find a sense of joy in things.

A child came up to me and asked 'am I dreaming?' I had a similar experience coming to the Art Gallery of South Australia when I was a child. My mum had done a workshop here and it stayed with me. It's an important formative time.

I pretty much keep everything; we have drawers full of samples and tests and every old catalogue and magazine.

In the studio we spend a lot of time working our what materials will work best and also last. We do tests and come back to them years later to see how they are still performing, and this leads our decisions.

I am particularly interested in the way that the everyday realities of the world around us change these relations.

Thinking is a social process. I talk to everyone from children to anthropologists and philosophers. I try my ideas out on people and they talk back to you. That's how ideas get formed.

Artists make worlds for people to walk through.
