Bluetooth handset
Take an old-style telephone handset, some miniature bluetooth gear, a bored geek, and you get… this.
It would be so worth it, just for the look on people faces… that is, until you get locked up and have to try and explain that you were just talking on your cellphone… really!
Next step, put the whole phone in one. All Class. I'd buy one, just for the novelty…
