The Desk Printing Calculator you see here looks pretty ordinary, but it actually holds a rather devious spy camera within. I guess with all these hidden spy cameras being crammed in devices of all shapes and sizes these days, it makes perfect sense to be more wary of gifts given by seemingly kind hearted folk at the office. It could be a devilish plot to unearth skeletons in your closet for everyone else to gain an advantage over you during the next round of performance reviews. Other than the spy camera functionality, the Desk Printing Calculator works like its normal brethren, performing standard calculations while printing neat receipts. This $529 device comes with a wireless remote control.
