So I was just surfin apple maps, checkin some places out. Well I decided to zoom all the way out so I could see the whole world. Well I've never seen this before iOS 7 (correct me if I'm wrong
-- I kno someone will!)... But anyway, it shows which areas of the world are dark (night time) or light (still day time). It also shows which areas at night have high populations due to the density of light. But ya this I'd have to say is pretty damn cool!
