Here is a model of the TARDIS (or a police call box) made of the cardboard from cereal (and other food) boxes and plastic packaging*. It also has LED lights and sound effects. Sorry this won't allow you to travel through space and time, yet.
Mike Hungerford: TARDIS Models--creator of the Steampunk version (parts from that are supposed to be interchangeable). This model might be taller/bigger than the other papercraft Tardis I have pinned--need to compare. May want larger size for some placements or to send home.
