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.

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.

Every lie creates a parallel world.. a world in which it is true

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 like the idea of doing things that only exist for as long as they exist, which are not archives, which are not sold or prepared even.
