Marie Rosen Wiberg is a teacher at Vasa Real school, in the well-off centre of Stockholm. She leads a project bringing her school together with kids from Rinkeby, an area of high poverty, unemployment and social housing. They worked together on a large wall painting, but the two groups of children had different attitudes.
She says the Vasa children's attitude is "me me me" while the Rinkeby children, used to looking after young siblings, think "we we we." The children created a long painting near central Stockholm's Odenplan Metro station, home ground for the Vasa Real pupils.
A bus ride takes us to the site of another painting, out in the suburb of Husby. The organisers have a vision that mural paintings can lead to positive social change. But Stockholm has a zero tolerance policy against grafitti, and Saadia Hussain tells me the state run companies that own the buildings were wary at first.
"There was quite a lot of fear...we had to cool them down. But it was based on trust. They gave us this wall and they trusted us."
Asking some young girls nearby what they think of the painting, "it's nice." But will someone come and paint over it, graffiti it? "No way," they say.
The painting in Odenplan is funded by Stockholm city's art budget. By local law every new building has to have one percent spent on art.
But this rule does not apply across the whole of Sweden. Katarina Jönsson Norling, of the artists' national association, says many local authorities have one percent on art as a spending target, but few live up to it.
Teacher Marie Rosen Wiberg says one of the girls from central Stockholm's Vasa School is still friends with a girl from Rinkeby School.
In this case the Stockholm art budget is having a very real impact on people's lives, bridging a geographic and class divide.
