As a computer professional and amateur astronomer I am all for any new lighting technology that will reduce light pollution. Ever see the poster of the USA at night?

As well as your CD player and your radio and your toaster......

I've never seen the poster, but would like to see it to satisfy my curiosity. Do you have a link, or can you post a pic of it?
