Illustrations like these do more harm than good. It lets people imagine that spaces are getting 'flooded' with 'stuff'. Radio is a light. A blinking light. A transmitting antenna like a light bulb. If your receiver can see the light blink (or a reflection of it) the signal gets through. Radio has the added benefit that (especially at longer wavelengths) most of the material world appears to be made of tissue paper.

Doesn't seem very legit to me.

Firstly, if wi-fi would be visible, you still wouldn't be able to see it all like we can't see visible laser ray unless there is dust/water/something in the air. It should be reflected from something to be seen.

But let's suppose it's just visible per se.. Ok, colors represent waves, but they don't look like 3-5 inches, more like meters on some photos.

Secondly, signal strength should dramatically decrease over distance. In two meters it should be four times as dark as in one meter, in 10 meters it should be 100 times darker.

Thirdly, on many pictures waves don't seem to disperse properly. Looks like everybody's using a very advance ridiculously narrow-range antennas.

I've been thinking about making a project out of this for a while. Lots of people have already hacked themselves to gain a "sixth sense" -- the ability to detect electric fields via magnetic vibrations. In today's world, wouldn't the ability to detect a strong WiFi signal be a bit more useful?

Realistically the result wouldn't resemble these illustrations at all; a simple signal strength -> vibration intensity converter would be more practical.

Now throw in all the radiation coming from everyone's cell phones communicating with the WAP, the numerous radio waves in the atmosphere, UV light from the sun, other sources I'm probably forgetting, etc...that'd be a much more impressive representation.

I don't know if these pictures make much sense really. Radio waves are part of the light spectrum but not part of the visible light spectrum, so it doesn't make much sense to represent it visually in this way.

If an artist pictured grass as if it reflected radio waves and not visible light waves, we'd have a interesting/weird picture but one without much value.

First, it's more of an art project than a science project. Second, it lets you see wifi strength! That's cool! NASA releases false-color images of stuff all the time, where they remap various wavelengths to visible colors. e.g. http://www.nasa.gov/mission_pages/voyager/pia00032.html
