An excellent short film on Transition Town Brixton now features on the Open University website. It was made, together with another about Transition Town Totnes by TTB film-maker James McDonald of Angeleye Films.
Just a note: this was made before the launch of the Brixton Pound on 17 September 2009. There are now more than 130 business accepting and trading in B£s and more than B£35,000s are sticking to Brixton and stimulating the independent local economy and the conversation about localisation.
