Fun in the frozen north

If I still lived in the frozen climes, I would so want to build one of these. Or rather, have someone build one for me. An igloo constructed out of milk cartons filled with colored water and frozen. It would even have to be an igloo. It could be a little tower and put a battery powered lantern in it at night. How cool would that be?
