Piano Tie Plays to the Geek Crowd

Taking wearable tech to ridiculous heights is the $9.99 Piano Tie, which touts itself as instrumental, so to speak, in making you "a hit at your next party." That said, this geek accessory is actually a lot more high-tech than it looks.

Sporting touch-sensitive polyester fabric, it's capable of playing eight notes. That's a whole octave plus an extra, which should let you perform classics like Chopsticks, if not Tchaikovsky. A plastic speaker hidden in the knot outputs your tunes, though we've no idea how long two AG 13 button batteries can last. An on-off switch helps avoid a faux pas when not impressing the guests.

As an encore, can we suggest whipping on the Air Guitar T-Shirt to end the party on a high note?
