Add a touch of geeky retro fun to your home or office with the Star Trek Door Chime. This gadget looks like one of the communicator panels from the original Star Trek but it functions as a door alarm for you. When someone crosses it’s motion sensor enabled path along the door’s threshold, the chime sounds either the “door opening” whoosh sound or the “red alert” sound. This officially licensed collectible is ideal for retro lovers, Trekkers, office drones and people who like their martinis shaken, not stirred (you know who you are). Whoosh.
