This tie makes a great gift for engineers, computer scientists, and fans of gadgets and technology in general. The circuit board pattern is printed on the fabric, but the lights in this design are fully functional, and flash in a variety of patterns.
I don’t think I’m brave enough to wear a tie like that in public, but I wouldn’t mind wearing one to work, say, on Halloween or something. In case you’re wondering, the “circuit board” is printed onto the tie. It’s just cleverly placed LED lights with the controller hidden in the rear pocket. $60 at Enlighted.
