Luis Hernan uses long exposure photography and an instrument called a Kirlian device to try and visualize the Wi-Fi signals all around us and it looks stunning.
Only used by geeks obviously.
The list of wireless networks nearby can be seen by anyone who has a device with a Wi-Fi module, so why not to make the network name funny or carrying a certain message?
You probably didn’t know that you can increase your Wi-Fi signal strength with a beer can. All you need is a beer can and these instructions.
I should definitely try this for my Wi-Fi network!
