Google's 3D building data for some cities (e.g. here in Edinburgh) is incredible - I'd tempted to get a 3D printer and work out ways of printing interesting parts of town.

Maybe my favourite mountains as well from OS data...

I'd love to see this for Scotland. I'd be tempted to buy my favourite Hebrides.

What would be really cool (at least for me) is to be able to print landscape models with geological data included as well....

[e.g. the Black and Red Cuillins of Skye]
