Tricky Model TARDIS

As you may know, Dr. Who's primary means of transportation through space and time (and many TV adventures) is the TARDIS. It's a sentient time machine, disguised to look like a 1950s UK police call box - but of course it's infinitely more than it's appearance. One aspect that comes up a lot is that the TARDIS (Time And Relative Dimension In Space) is much bigger on the inside than it appears from the outside - or maybe it's just much smaller on the outside? In either case it seems reasonable that if you made a model TARDIS, you would aspire to find a way to show off that feature - and thats just what Greg Kumparak did!
