What do you get when you start with a white room and then give thousands of children coloured dot stickers?
That is exactly what artist Yayoi Kusama wanted to find out.
She painted a room in the Brisbane Gallery of Modern Art completely white.
The walls, floor and ceiling were white. The piano was white. The couch, TV and seats were white. Even a fern was painted white.
And then she invited thousands of children inside.
