Stellarium. A free program which renders realistic skies in real time, and more. Handy for anyone who ever wrangled with one of these. And very cool to watch in fast forward.

So maybe rolling blackouts are a good thing. "Light pollution" means we don't see the universe today that we saw it when we were kids. What's the balance between being able to see that hazy something we know as the milky way (aka "us") and safe streets, aesthetics and convenience?
