Is this the next step in portable music technology? Or maybe the next big thing in fashion? Probably not. But it is incredibly impractical, and pretty funny. An artist at Parsons The New School for Design in New York has created Play-A-Grill, a jeweled frontpiece for your teeth that actually plays music inside your head. When the music starts, the vibration is strong enough that the music can be heard clearly without the need for headphones. If the sound being played is loud enough, others can even hear it apparently coming out of your teeth. INCREDIBLE!
