The painting campaign was funded by Palestinian investment company Padico. It is the latest and largest of four similar initiatives to color Gaza's neighborhoods ravaged by last year's war. Artists said the effort was inspired by similar projects in Mexico and Venezuela.

"It's a voluntarily work to bring joy and happiness for our families and children in the Shati camp," said Mohammed Dahman, a painter who worked for a month on the project.
