Neat! I'm going to use this to share a link to my thoughts. Call me if you want to hear it.

It works! And the sound is very funny.

Reminds me of a few years ago, when a security researcher discovered a virus that used this same technique to communicate with machines that didn't have internet connections. They couldn't believe it at first: completely isolated computers with a seemingly supernatural ability to receive instructions.

And now Google's made a plugin based on the same idea. Fascinating.

How very obnoxious.
