If you were wondering what the sonic was all about, it was a weapon used by the Eleventh Doctor to scan Teselecta and contact Amy and Rory while they incubated inside.
The Sonic Cane emitted a green light and came with four claws that opened in order to reveal the light. Ironically, the sonic screwdriver featured in Eleventh Doctor featured the same characteristic as well.
Jud Hudson at DoctorWho has come up with a handcrafted Eleventh Doctor’s Sonic Cane, which looks almost perfect. It is based on the one from Let’s Kill Hitler and the weapon looks quite formidable. He admits that it is not his best but that he tried pretty much. We feel it is a great result nonetheless and can even fetch a decent sum if he tried to sell it in a toy store.
You could also go ahead and take a look at the Doctor Who Boardgames, which is a great way to spend a boring Sunday afternoon. If that does not suffice, you could go ahead and take a look at the Doctor Who Tardis poster which can be hung against a wall in order to tell everyone who visits your home that you are a really huge fan of Doctor Who and all the characters involved in the series.
