Okay, we already have:

• A TARDIS
• A printable dalek, a 3D rendering of a dalek, and a dalek head
• A sonic screwdriver for the 1st, 10th, and 11th Doctors1
• A cyberman symbol
• A dalek, TARDIS, and sonic screwdriver cookie cutter2

What else could we have?

• A time lord seal
• K-9345
• The Pandorica
• Sonic screwdrivers for the 2nd, 3rd, 4th, 5th, 6th, 7th, and 8th Doctors
• The Doctor’s calling card from The Remembrance of the Daleks6
• A time vortex manipulator

I should really include links to all of those…

1. Well, most of the 11th.  It’s a perpetual work in progress. [↩]
2. Delicious sci fi???  Sign me up! [↩]
3. Canine?  OMG!  I finally got that joke! [↩]
4. And it only took me 26 years! [↩]
5. Wait, wait, wait… K-9 Unit?  How long has this been around??? [↩]
6. This is one of my favorite episodes, if for nothing else than the flippant bit about the unlimited rice pudding.  The Doctor leaves a little calling card for no apparent reason, but it is kinda cool.  I had this episode saved on VHS.  My brother taped over it with a Barry Manilow special.  It’s still quite a sore topic for me.
