Sonic Fabric Neckties Are Actually Playable

The music may be horrible, but if you rub a tape head over these ties you can actually hear jumbled sound collages recorded from the NYC metro system. This is possible because the ties are 50 per cent audio cassette tape.

If you have $US90 to spend on one of the ties, and you are willing to sacrifice an old Walkman for the project, you can make this a fixture of your formal wardrobe. Of course, walking around with a broken Walkman asking every one to rub you with it is not recommended. [Supermarket via Gadget Lab]
