"I have a dream" at HacDC.

A couple of weeks ago at HacDC Dave Monachello, an electronic artist and frequenter of the infamous gather known as Burning Man presented one of his latest works, an animated electroluminescent wire sculpture depicting Martin Luther King, Jr. Multiple layers of EL wire were attached to a translucent backing material depicting parts of different facial expressions associated with the act of speaking. The EL wire was rigged up to a bank of microcontrollers which triggered the different layers as a frame animation in time with a recording of King's I Have A Dream speech.
