A TARDIS is a product of the advanced technology of the Time Lords, an extraterrestrial civilisation to which the programme's central character, the Doctor, belongs. A properly maintained and piloted TARDIS can transport its occupants to any point in time and any place in the universe. The interior of a TARDIS is much larger than its exterior ("It's bigger on the inside"), which can blend in with its surroundings using the ship's "chameleon circuit". TARDISes also possess a degree of sentience (which has been expressed in a variety of ways ranging from implied machine personality and free will through to the use of a conversant avatar) and provide their users with additional tools and abilities including a telepathically based universal translation system.
Lets go to the TARDIS.

The TARDIS apart from having the luxury of time travel has an added feature of having an interior of infinate size contained inside a very limited physical space, this is due to the dimentional rift on the boundarys of the TARDIS front doors.
When you enter a TARDIS you are steping out of your reality and into another through the dimentional tear in space.
One disadvanage is, although it has so much space inside theres not much you can fit throught the doors... unless everything is flat-packed (see IKEA)

A device often wished for by software developers who have been given unreasonable deadlines to complete their work. Although typically this would be used to give the benefit of hindsight to oneself in the past, many would wish to use it to kill the parent/grandparent of the project manager, thus ensuring they will never have been born.
Uh oh, we're going to miss our deadline, everyone in the Tardis. Boss, you stay here.

1) Acronym for Time And Relative Dimension In Space. Spaceship owned by the Doctor from Dr.Who, with the ability to travel through space and time. Takes the form of a 1950's British police box, although this is merely because the camouflage unit is malfunctioning. The TARDIS is also a lot bigger on the inside than on the outside, theoretically, it can be infinite in size.
