This in turn led to Ms Hobson, head of senior art at Greenacres school in Nairobi, Kenya, setting up the Through the Eyes of Children project, a snapshot of children's lives worldwide on January 31 this year.
Collaborating with two of her students, Evelyn Byaruhanga and Pauline Kamu, she persuaded photographic equipment supplier Fuji to donate 100 disposable cameras. These were sent out to schools across the world, with loose instructions to shoot pictures of the classroom, local transport and buildings, more abstract ideas such as friendship or happiness, and anything else of interest.
The films started returning in early February, and Ms Hobson says: "The project has just snowballed. We planned an exhibition and website for June, and with the films still coming back in, we have already had two book offers."
