Calling all artists

Settle in North Yorkshire claims to have the smallest art gallery in the world.
Here it is, a disused phone box bought by the town council in 2009 under BT's Adopt a Kiosk scheme and transformed into a community art gallery.
Anyone is free to exhibit their work, locals and visitors alike. And according to the website the gallery is open 24/7 and filled to capacity at least twice a day.
