NUKEMAP: So You'll Know What To Expect If Your House Ever Gets Atomic Bombed
NUKEMAP is a Google Maps application created by Alex Wellerstein (who may or may yes live in a fallout bunker) to visualize the area affected if a nuclear bomb was dropped in your neighborhood. You just choose the size of the atomic bomb you want to drop (or a historical preset), enter an address (or drag the nuke icon) and BOOOOOM, everything you've ever known and loved is dead. Unless you blew up New Jersey, in which case hopefully it'll just break off and float out to sea.
Thanks to Little Nicholai, who doesn't believe in atomic warfare. Atomic fireballs, yes. Man, those things f*** my mouth up.
