Datashine by @oobr puts UK Census on the map - Warning: Not Safe for Property Porn Addicts

This is sensitive stuff, so not going to say anything other than take a look for yourself: http://datashine.org.uk/#zoom=11&lat=51.54625&lon=-0.24647&layers=BTTT&table=QS111EW&col=QS111EW0015&ramp=YlOrRd

If it's too much for you, CityAM give a good synopsis: 

This sort of project shows just how accessible you can make reams of seemingly dry data. Effectively, DataShine is to the Office of National Statistics what CityMapper is to Transport for London - after endless struggles with the official institution, a relatively small outside operation has managed to display the information in a much more useful way.
