By the time I finished the book [All Alone in the Universe], Robin Roy was saying, "More pictures!"

I don't think about it that much, but sometimes I am surprised by that. I sometimes wonder why I didn't turn out to be the kind of picture-book writer who has stuffed animals that go with their books. That would be okay with me.

It's one of my favorite times of day. I'll have an array of notes, things that I want to think about. Something will start to take shape, and I'll play around with it. It's not usually an intense time. It's sort of a playful time. But it's when some really good thoughts arise.

There will be scenes in a movie where people are walking through the park, or through a forest, and you're seeing the flickering leaves around them, and they're walking, but you're also hearing their words. It's an interaction between where they are and what they're saying that's both visual and verbal.

I'm German, after all.

Ideas mostly come from the work itself. Often when I'm drawing, the words will be bouncing around in my head, and when I'm writing, ideas about the drawing happen.

I knew what infinity was. Being a previous art student, I knew about some art concepts.
