I became obsessed with making more and more tiny things. I think I was trying to find a way of compensating for my embarrassment at having learning difficulties: people had made me feel small so I wanted to show them how significant 'small' could be.

People find it very, very difficult to believe what I've done. Scientists have seen my work and they can't explain it. Even nano-scientists have seen it and been totally shocked. But if any man on Earth wants to challenge me, I'm ready. Bring it on.

Flying helicopters is what I do for fun.

At school I'd want to be so small that nobody could see me, and so my work depicts and reflects me - what it felt like to grow up in a world of pain.

As a kid, I lived in a fantasy world. I used to believe ants could talk. Not once did they say thank you.

When I first heard that Barack Obama was going to be the first black president, I wanted to do the smallest, biggest tribute in history.
