From Beth's Blog: Step into a Van Gogh Painting in Second Life.
Looks quite fun, though I haven't signed up to SL so I dunno. I was thinking about how one might be able to use the power of that new application for extracting 3D data from 2D images to interpret paintings, and at least get a head start (and better textures) for something like this. No idea how that would happen, but it has to be said that though this van Gogh reconstruction is nice and potentially useful and instructive in itself, it's pretty far from the painting.
