I found this posted in a forum which gave me the idea for my recent post. According to the poster, this is a capture of a his friend's roommate who always walks around naked. He left his laptop on their dinner table and and got this. From what I found out the key to pulling this off is recording the video from a stream to another computer (like a desktop). That way you can minimize the webcam software while broadcasting and get candid captures. It simply looks like the laptop is on.
