I try to make that tension almost stupidly overt in my projects, almost ridiculously so. I keep coming back to the same obvious points again and again.

Dutch beaches were known to me as man-made territories, as part of various land reclamation projects. But I was also interested in the media reality of the Moon landing. I wanted to use that event as a measure of time, to see what had happened in those thirty years - which happens to be my lifetime as well. I was born in 1967 and I remember seeing the Moon landing on TV when I was two. All those things were in play. Then it became a big production. It took five months to gather up the goodwill and make it happen.

I've made a poster at home. You know the iconic image of Che Guevara, the black and red graphic of his face? I think it's the perfect graphic, the best graphic ever made. I cut a Concorde out and put it over his head so it's Che looking up and the Concorde going by. Both are dead, maybe obsolete.

I wouldn't say the anthropologists were making art, but they were definitely justifying their practices with very personal reasoning, passion, and they were also experimenting with form. There was a sense of trying to be as sincere as possible, whether you were investigating something far away from you or very close.

I'm very jealous of an era where people were inventing something so beautiful as the Concorde and thinking that's the next step. I'm jealous of an era when people thought, "Let's finally go to the Moon."

I'm so extremely well prepared for negative response, I've taken precautions.

I wanted to contribute to the landscape tradition in art. By now I guess we are comfortable with the thought that man has been everywhere or affected everything in nature.
