Think Geek brought a little Star Trek cheer to us today with the Star Trek Electronic Door Chime. It has two settings, the classic door chime, and red alert that activate via motion censors when someone enters. Modeled after the original series panel, this is sure to be a great housewarming gift for your dear nerd friends. Hey this might even come in handy at work. Give everyone a heads up to know when the boss comes in with a red alert. Available at Think Geek for $29.99. I’ve got to finish this article so I can go buy one before they are all sold out.
