Children's Laureate Anthony Browne has created a special book for the Rainbow Trust charity, called Play The Shape Game.
In it, 45 celebrities, authors, artists and illustrators, including Harry Hill, Quentin Blake, Jacqueline Wilson and Emma Thompson, have taken the same shape and turned it into their own piece of art.
This is the shape Anthony Browne gave the celebrity artists
They've also created shapes for you to transform.
Profits from the book will be donated to Rainbow Trust, a charity that provides vital support to families who have a child with a life-threatening or terminal illness.
Last time we spoke to Anthony he told us what he wanted to be apart from an author (boxer or journalist) and what inspires him (fairy tales). This time we got him to answer some more of YOUR questions.
Here's what he had to say...
Who or what inspired you to start writing? Shona, 11 & Millie, 10
I've always loved drawing and making up stories. When I was very young I lived in a pub and apparently used to go into the bar, stand on a table and tell stories to the customers - usually about a character called Big Dumb Tackle. I also used to draw every day.
Both my parents encouraged me in anything creative.
When I was an adult I saw Maurice Sendak's Where the Wild Things Are, and this showed me what's possible in picture books.
What does it feel like to be the Children's Laureate? Hannah, 9
It feels great!
I'm very honoured and very busy - trying to encourage people to value reading (words AND pictures), to encourage us all to really look at the world, and to develop the creativity that we all have when we are six.
What inspired you the most to take part in charity work and why is it important to you? Rebecca, 12
Most people enjoy helping others and I'm no exception.
What are your favourite poems and why? Anna, 12
One of my favourite poems is actually by an illustrator, Colin McNaughton, and it's called How Many Fish in the Sea, Dad? I think it's very funny and also very touching.
I have noticed that your books My Dad and My Mum focus on the relationship between parents and children. How have your own experiences as a parent shaped what you have written? Maddy, 13
It's difficult to answer that question as there doesn't seem to be a change between books I made when I was a parent and books I made after.
I know that when I started work on My Dad I had become a Dad myself and found it quite hard to make a book about a warm, loving father. I think it was because many people think that my main characters are a version of me and I felt as if I'd seem to be boasting.
Then I found my own father's old dressing gown and that inspired me to base the book on my feelings for him.
