Whereabouts London (a 2014 team project I was involved in at the Future Cities Catapults) focused on exploring how open data could be used to improve future cities. The boundaries within London have been split and merged over hundreds of years. The project tried to find out how the city might look if we drew them afresh, grouping neighbourhoods based on whom lived in the localities.
The project gained some interest from the Economist Magazine. That article is available to read here. https://www.economist.com/britain/2014/10/30/city-slicker
