Taking Virtual Stock of Old Stockholm

It's coming:

These drawings and architectural plans would actually be an amazing resource for a virtual reconstruction of historic Stockholm, built with SketchUp. The drawings could provide both shape and texture to 3D buildings, while the maps pinpoint location. You could then fly around an accurate 3D rendition of Stockholm as it was documented hundreds of years ago!

And if the conversion tools mature, as I have no doubt they will, you could soon port all this work into Second Life, and then walk around in it, wearing nothing but 18th century fashions.
