...then it would probably look nothing like this:

Standing waves, anyone?

Now just position the WiFi source on a second nearby mill, and animate 
the thing!

As you do. :-)

One question, though. What does "and there's an application on my 
computer that looks at the Rx power of those pings and...", mean?

I *think* he's saying he has an application that sends out ping requests 
and measures the radio amplitude of the reply, as reported by the WiFi card.

That's what I thought he said. So he is using the received power of the 
Sensor's transmission to send a colour signal, to the sensor. As a 
visual indicator of the Rx signal. Then he analyses the data by 
photographing the light source.

Ladies and Gentlemen. As you can see.
I have nothing up this sleeve and nothing up this sleeve...

I liked it though. :-)

Dang - that guy just wasted a great topic for a scientific paper on a
youtube clip...

Pfft. You think the people designing the WiFi protocols don't already 
know that standing waves exist? ;-)
