Video Camera Pen
There comes a time in every geek's life that he comes around with a gadget that holds great potential for power! Whether it is used for good or for evil, does it really matter? With a Video Camera Pen you can actually do just that.
With a small, concealed video capturing device, the budding spy, detective, or villain can record video of things that you don't want other people to know you are recording.
Perhaps you need to get some video evidence in the name of the law. Maybe get some evidence of a drug bust for instance. Or you could record "home" videos of intimate moments, for the purpose of preserving memories and in no way share online. Or you could capture funny candid video clips in a family outing for the purpose of posting online. The limit is your imagination and technically the 2GB memory that comes with the device.
