Video LED lights can hear your voice

Skip to 5:12 if you wanna hear sound from LEDs.

It's pretty fascinating. Not much of a threat though because of smartphones.

from the description:

EDIT: I may be misunderstood, the description should read "An LED light can be used to transmit audio", many people are misinterpreting this to mean that the led can actually "pick up" audio like a microphone, this is not the case.

still, this is pretty neat
