Skype Laughter Chain

Skype is a software program created by Niklas Zennström and Janus Friis. Skype allows users to make telephone calls from their computer to other Skype users free of charge, or to landlines and cell phones for a fee. Additional features include instant messaging, file transfer, short message service, video conferencing and its ability to circumvent firewalls.

Now, Skype has launched the Laughter Chain. They're creating the world's first and longest giggling fit, and they want you to join it. Just plug in your webcam, watch the start of the Laughter Chain video, and film yourself watching it. Send them your video and your laugh could be added to the chain.
