The CIA (yes I'm aware the CIA is different than MI-6 where Q works...but Felix Leiter doesn't have as many witty quips) has started a Youtube channel and a Flickr stream all about itself. Including its history, spy gadgets and never-before-public knowledge. Below is an example of what I'm talking about. Its a covert letter-intecepter which allowed an agent to remove a letter, read its contents then re-insert without the sender or recipient knowing it had been tampered with. This was done by grabbing the paper from the inside and rolling it up, then reversing the process afterwards.
Other devices include this tobacco-pouch disguised mini-camera (pictured below) and robotic catfish (further below that). I love this kind of stuff, seeing how small they can get a normal gadget, or combining functions of seemingly different devices. Needless to say, the CIA's equivalent of the Q-branch probably does get some inspiration form Bond movies.
