To celebrate my newly again found status as Master, I'm posting this for you all, and especially Tarun. Here's a printable cut-out to build your own Tardis. All you need do is print, build, and enjoy.
1. Send your pet gerbil back in time, allowing it to fundamentally change the genome of the species through evolution, thus leading to a dominant race of super gerbils covering the planet.
2. Keep hidden away until that really annoying and scary looking women asks you for a date again, and then bring out the Tardis, making sure to spend no less than 60min explaining how it works, its history, and why it looks like a police box. I guarantee she won't want to date you after that level of geeky has been shown off.
