Will Gompertz vlog: Can artists improve our world?
This week saw the Turner Prize exhibition opening in Glasgow.
It's one of the most high profile events in the art calendar. One of the shortlisted candidates is an architectural collective called Assemble.
They are among a growing band of social activists who work with communities to regenerate economically-deprived areas.
In his regular vlog, Arts Editor Will Gompertz considers whether artists and artisans can really improve our world.
