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."

The space program caused so much future-thinking in culture. People who couldn't go to the Moon were building space-fantasy chairs and corsets and hairdos and anything that they could put their hands on.

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.

There are ends, occasionally, with projects. That happens. But they are natural dead ends. It's usually the outside situation that demands an ending. I never really settle for one.

"Naming Tokyo" kicked off at the Palais de Tokyo in Paris in June, and it's going to travel to various art institutions for years to come. Every time it is shown, I'm developing the research and involving more and more people in it. The final conclusion of the work would eventually be to put up street signs in Tokyo with my names on them.

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

Of course, I'd welcome protest. Good criticism is hard to find.
