As I way passing through Oakland, CA on my way back to the UK last week I made a diversion to do one of the stories that's been in my Long Term Futures file for an age.

Creative Growth is the world's oldest and largest art centre for adults with developmental and educational disabilities and a powerhouse of what's been termed "Outsider Art."

As the Guardian recently pointed out, the concept of the outsider artist can be an unsettling one.

Still, Creative Growth is a fascinating and inspiring place and some of the artworks produced there are truly amazing.

My article on the centre will appear here in due course.
