Found this on teh interwebs:
- Not Possible IRL: Geek heaven: A wiz-bang geo-coded map – and a news source, too – "Corro Moseley (aka David Burden)? has teamed up with Ian Pahute (aka Ian Upton) to create a geo-coded map within Second Life® that enables you to explore a scaled 3D version of Birmingham." Not going to install Second Life, but screenshots look good.
