Using an augmented reality app and a 3D rendering of the TARDIS's interior (as it appeared between 2005 and 2010), tech writer Greg Kumparak took an already-impressive model of The Doctor's time&spacecraft and endowed it with perhaps its most commented-upon feature: an impossibly spacious interior.

Kumparak explains:

I've spent the last few months tinkering with all sorts of little projects in an effort to learn to build awesome things. Most of the projects were intended to be scrapped from the get-go, meant primarily to help me wrap my head around some concept – brain fodder, if you will. With others, I was testing the water with ideas I might want to flesh out into proper ventures down the road.

With a few of'em, I was just putting things I'd learned together for the sake of just making something cool, viability be damned. This is one of those.

I built a TARDIS. With the help of some augmented reality trickery, it's bigger on the inside (as any proper TARDIS should be.)
