Idea 1 - TARDIS

“The TARDIS (Time And Relative Dimension(s) In Space) is a time machine and spacecraft in the sci-fi TV series, Doctor Who.”



Outside, it looks like a British police box. On the inside however, it is much, much bigger. It takes the form of a massive room with a control console in the centre.



Could use this as a theme. The door is made to look like the outside of the TARDIS, and then the room itself is the inside of the TARDIS.
