So you are an aspiring spy who harbors ambitions of keeping a close eye on your arch nemesis? The ZRAD pen camcorder comes with a built-in video camera in addition to looking (and functioning) like an ordinary video camera. While it doesn't have any storage capacity of any sort, it is capable of sending both images and audio sans wires to a computer or other receiver for display. Unfortunately, only black-and-white images are captured so you can forget about an accidental but award-winning voyeuristic shot. This camera pen retails for $300 a pop.
