Mapumental is a fascinating new project by and 4iP that builds on’s earlier work on data mapping.

Feed it a UK postcode, and it will generate an interactive choropleth map, which lets you see locations highlighted by public transport commute times, house prices and ‘scenicness’.

The service is in private beta at the moment. (My invitation arrived immediately after signing up, but the site is a wee bit slow, and prone to serving up error messages instead of maps–clearing cookies fixed everything for me, but your mileage may vary.)
