lol - now expecting people on an internet forum to actually read and comprehend your question - is being a bit unreasonable ;-)

From an insulation point of view then a 2 part print you could fill with polystyrene would be simplest.

I did notice that shapeways also have various binderjet machines includign the new(ish) hp one. So would be able to print in both full colour and quite finely textured surfaces.
By creating a model with a textured surface you can easily create a stone or ceramic like appearance.
With the hp machine you could not only have a textured surface but also full colour artistic decorations.

Before you decide, get a quote for something of a similiar size - 'cos it won't be cheap !
