Speech to LED matrix marquee (Voice2LED)

Connecting a LED matrix to a computer, so you can program any text from computer to the LED matrix in real time is not new, but Josh got another cool idea combining the use of Google Voice.

Basically, you can dial to the Google Voice account and leave a message, the Google voice engine will convert the speech to text and send back to Josh's LED Matrix:)
