If the apocalypse is nigh, do you want a text alert?

Artist and coder Kyle McDonald has created an apocalypse early warning system. It tracks billionaires' jets to see if they are fleeing to their private doomsday bunkers. If the end really is upon us, it won't save you. (The super rich will probably be toast too.) But he hopes the social commentary it provides might make you feel less helpless and nudge you to do something about the mess he says we're in.
