Nothing's cuter and more awesome than a geek couple's wedding. Circuits and Swirls - turning a paper invitation embedded with circuit boards that light up when opened. That's nice! That's what Bill Porter and his fiance Mara decided to do.

Bill talks about how he built his wedding invitation, where he made use of a microcontroller-powered blinking LEDs with a small battery and a light sensor.

Check out the video below for it. The only this could have been more geekawesome was that if it was all in Morse code.
