Can’t be sure who is stealing all the cookies from the jar every night? If you have some DIY skills, perhaps you could hack together your own motion-sensing spy camera rig and capture the culprit, which is precisely what someone out there did, hacking together parts from an Air Wick Freshmatic, a cheap keychain camera and an MSP430 microcontroller. Once finished, it looks pretty good and hopefully will solve the cookie mystery once and for all.
