If you work in a public space, you have to be aware that no one is buying a ticket.

In Holland, we have a saying: 'A knife cuts on two sides.' With the rubber duck, I'm trying to show people what they haven't been seeing in their public space. When the rubber duck is there and when it's gone, you know.

I want people to get inspired by public space - their space. People tend to forget about it because they do the daily thing, but putting up these sculptures breaks the routine.

That is the effect of my sculptures in the public domain: people are making contact with each other again.

I make work a bit like how you mix cocktails - with ingredients like budget, history and location.

I make work not to give answers but to question things.
