Urban Revitalisation Projects

Collection of some organisations/people involved with creating interesting urban environments:

Rebar
A group from San Fransisco, very inventive and edgy approaches to the built environment. Creators of the Bushwaffle and the Annual Park(ing) Day. Can be looked at as a business model. They work as fee-for-service as well as for community causes. They articulate their position very well through their online content:
"the development of urban and social abundance" and "We do business in both free-for-service and social benefits contexts"

Smart City
A group of universities continuing the discussion into the occupation and planning of cities. They have similar aims to what may form to create the CitySwitch Lab:
"power of citizens + inclusive visioning" and "improved professional support of the viable future"

Urban Screens
An example of the specificity which can be present in the way that cityswitch function as a business. Should it be consultancy on one very specific element of urban revitalisation or broader. How do we formulate a format which can clearly articulated as our role in an urban environment?

Urban Art
Distinct from the above two projects, these are not specifically liked with urban revitalisation however utilise the urban landscape as not only a canvas but also an interactive space.

Banksy
British Graffiti artist who's work is not only amazing in a graphic sense but also in the way it plays with current political, cultural and social issues. Very well known around the world and who's work now is worth thousands of pounds.
