ART is not only used to brighten a bare wall.
Research has shown that an optimistic or happy attitude reflected in an artwork can lift one's mood, and play a vital role in the recovery and healing process of a sick person.
Operation Art, an initiative of The Children's Hospital at Westmead, in collaboration with the Department of Education and Communities, involves school students from kindergarten to year 10 creating bright and colourful artworks designed to cheer up children in hospital.
A record 897 works, including paintings, drawings, mixed media, print making, photography, fibre and electronic pieces were submitted by NSW students.
Lucinda Vanderklauw, Sooin Cho, William Bello and Yash Goel of Castle Hill Public School were four pupils chosen to have their masterpieces displayed at this year's exhibition at the Armory Gallery in Sydney Olympic Park until October 27.
Lucinda, 7, created a bright rainbow using crayons and paint.
Sooin, 7, drew an undersea adventure featuring sea creatures.
William, 8, used chalk and crayon to create a creature called "Moducker" — a combination of mouse and duck body parts.
Yash, 5, drew a giraffe playing an electric guitar in a field of flowers.
Yash said he hoped his artwork would make people happy, especially sick kids at the children's hospital.
"The giraffe is very funny and he has this really long neck," he said.
"I think because it's really funny that it will make them feel better."
Up to 50 works will be selected to become part of The Children's Hospital at Westmead's permanent collection.
