Thanko's USB Video Necktie With Built-in Spy Camera
Thanko says video will be shot in 640×480 resolution at 30fps and stored on the 4GB internal flash memory (1GB is enough for 30 minutes of video, according to the company). The camera is powered by a button battery, and needless to say (this is a Thanko product, after all), there’s a USB port, too.
The gadget is already available in Thanko’s Japanese online store (for $120). Ask specialized shopping services like the Japan Trend Shop or Geek Stuff 4 U if you’re interested but live outside Japan.
