That's awesome, thanks for mentioning and the links, Micheal. The printing will probably require either a set of renders around town to feed the point-cloud, or a conversion of the objects and terrain to closed, printable 3D architecture. For a small A4 sized diorama the first would be quite feasible, I think. The latter not. But expensive, no doubt.
I'll mention it, see what they think. But I think they want to go for 'an experience'. The holographic stuff is awesome, but too private I'm afraid, and probably very expensive still.
