From brilliant photographer Benoit Paillé
How do we determine what our WiFi landscape looks like? One way is to create an LED rod that turns more light on, the stronger the WiFi signal is, then walk around and take extended exposure shots. Timo has done just that. More here on his page. Video Source Page Here.
Nothing short of brilliant, this image search site is based on color. Play with this, see how amazing it is, pick the weirdest color combination you can find and see how it works. Once you find an image, click on it to visit that image in flickr.
This is why we should mind our light pollution. This extraordinary photograph was taken by Barnaby Norris and it shows what the universe can reveal in total darkness. It’s ironic that by turning on the lights we should become blind. Please support Dark Skies so we can see again.
