Share 'YackPack Walkie Talkie Widget for Cities Around the World Project'

This widget allows one to talk when the press the button, and listen when someone else is pressing the same button, I think. I'd love to test it with someone so let me know if you're up for it. I put this walkie talkie thing on the front page for the Cities Around the World wiki (https://citiesaroundtheworld.wikispaces.com/), too, so that project participants might chat with each other.
