- Smaller on the outside (probably will work by teleportation or something)
- Full length model (the model will be around 3-3.5 blocks high)
- Will be able to fly anywhere (probably a tacky little formspec GUI :3)
I'll really need someone to help me with modeling the inside of the TARDIS though (I have a server, PM me for details).
