Wonder or surprise I evoke especially by using everyday materials and simple techniques. The viewer should really be able to make it himself.
When does something become art? How many holes do you have to cut in a sheet of paper, or how must you hang up a branch, or place a stone. With a small intervention you can suddenly change something ordinary into something quite different, I am still amazed by this. In fact I am always searching for the turning-point – the moment when a stroke on a piece of paper changes into a bird. That is the point where people can step into their imaginary world.
