Recently, I gave a suggestion to Tim [Theta Sigma 11235] here on DeviantArt regarding the doors of the Tardis, and this little idea of mine his used for a brand new Video which he uploaded for New Years Day. Here's my suggestion I gave to him recently. Best to read it first so you understand what the Video link below is all about.
Got an idea for you actually that maybe you might want to consider given a go. Basically, I wondered how it would look if the Tardis's Police Box doors are seen opening from the outside, and we see what is directly in front of us looks like the wall of a Police Box directly infront of you as if you was looking inside a real Police Box, but suddenly, the back wall inside the Police Box opens up, and it turns out to be the classic series Tardis doors which uses one side of it's doors to look like the back wall of a real Police Box when viewed from the outside with the Police Box doors open.
If you remember the story 'Father's Day', the 9th Doctor opens up his Tardis, only to discover the entirely inside of his Tardis is gone, leaving just the Police Box interior looking like a real one . . but what if the Tardis made it look as if the Tardis had it's original Tardis doors back, and the otherside of those larger doors kind of matches the Police Box wall seen in front of you when opening both Police Box doors, using it as a kind of camoflague to make people think they really was just looking at a Police Box if someone really did manage to open the doors without a Tardis Key or have the Doctor do it for them.
I hope you understand all that. Just an idea offcourse. I thought about it whilst looking at the open doors in this latest upload.
