If you're a poet and you're using rhyme, rhyme generates ideas. If you're a songwriter and you're using melody and words together, they bounce off each other in interesting ways that you couldn't get otherwise, because you do things unexpectedly.

When you tell filthy jokes as if they were all really serious, and happening all in the life of one family, it becomes a farcical situation. Imagine if you had a script that was imposed on your life - we all do in a certain way, from society, or family, the need to make money, biology, death. But you will have a certain latitude, or freedom, to read the script in your own way.

Pablo Picasso said, "Art is the lie that tells the truth," and it's not a terribly radical statement. It's always been that you can tell truth through fiction. And this idea also comes from nuclear physics.

I'm bored with DJs. Anybody that puts the title DJ in front of their name immediately turns me off. I prefer the term "sampling," because it has both the dilettante side, like someone tasting wine or caviar, but also functions as a kind of litmus paper dipped into culture. And the whole semi-legality of sampling is very interesting as well. So a DJ is not really creative enough for me to be an appropriate metaphor.

If you look at the steps being taken towards Scottish independence, they're being dealt with politically in very dull and boring ways. So if you just feverishly speculate numbered but random Scotlands - because in the book, it's a random sequence of possibilities - you can imagine many ways in which different things might happen.

Quantum physics says that there is an infinite number of possibilities and parallels to the one that we know, and every event is also played out in a parallel world. It's kind of a crazy idea, but someone called Saibal Mitra at the University of Amsterdam says that if you could back up your memory in case of a catastrophic event, you could actually revert to that back-up and find an alternative world in which the Earth didn't explode or collide with Mars.

Design is interesting because it's utopian. Art is often a jaundiced commentary on contemporary life. Design is always about the future; it's always about something great and new that's come out that will make the future brighter. It has this weird 18th - century positivism about it.
