New technology speakers made from carbon nanotubes.

Carbon nanotube speakers have been created; by sending an audio-frequency current through a carbon nanotube thin film, it can be made into a superthin high-performance loudspeaker that emits sound in a wide-frequency range. The carbon nanotube speaker functions without any moving parts or heavy magnets.He notes that, when fully stretched, the nanotube speaker became transparent, causing the team to envision attaching it to the front of an LCD screen in place of standard speakers. Some of the more ?exotic uses? they dreamed up for the speaker, he says, included the possibility stitching it into clothing to create a kind of ?singing and speaking jacket.? ====================================================================
Pretty darn trick if you ask me. Wasn't the subject of machining carbon nanotubes just raised recently.
