Magic Item Writeup Challenge

[Aranai]

So some friends of mine and myself were talking about fun magic items to have Wizards build, and we came up with one we just couldn't solve*. Granted, the entire idea of this is just a joke, but I'd like to know if it would be possible within the rules without a GM fiat.

How would a Wizard build a TARDIS? What component pieces would be necessary? I'm not extremely familiar with Doctor Who, I've only really seen the new series. Barring things that aren't possible without being plot-integral (such as time travel), what would the closest approximation be?

*The issue we couldn't figure out entirely was the time travel issue. I'm pretty sure it relies exclusively on fiat.

Apparently, there's little interest in htis.

All I can tell you is this is a Ninth Level Power from the 3.5 Expanded Psionics Handbook. 9th level powers are basically 9th level spells, so traveling back in time for one round is beyond even the "safe" use of the Wish spell.

Traveling forwards in time is a 3rd level power, duration 1 round/level; mechanically it's Hold Person + Blink, with a little added safety (you never reappear inside things).

In other words, Time Travel = Minor Artifact at the minimum. Which might be why you're having trouble figuring out the mechanics.
