This is really neat! Especially useful if you want to do some stargazing and want to find the nearest location with dark skies. On a related note, my alma mater is now home to an initiative called "The Consortium for Dark Sky Studies" (CDSS) [0]. Their mission appears to be promoting the development of technologies and techniques to preserve (and possibly reclaim) the darkness of skies. I don't know much about how they're planning to accomplish this exactly, but I think it's kind of a neat idea to at least raise awareness. [0] http://darkskystudies.org http://darkskystudies.org
