That's really cool! I haven't tried making the inside of a Tardis yet. So far, I've just used the blue locker to be the outside. But the main thing I did was dress up my BV avatar to look like the tenth Doctor. I'll keep an eye out for other props that can be made, though.
Hey, thanks for the message! Just saw your thread and I love that your story mentions the Doctor and the TARDIS. Always love seeing other Who fans on BV!
