In Frequency, the latest XKCD cartoon, Randall Munroe has assembled a grid of animated GIFs representing various events in the universe, each keyed to blink in the frequency in which they occur in reality. As with the best of Munroe's work, it's a mix of the trenchant and the silly, and the juxtapositions are smart and provocative. There's real genius in putting "50,000 plastic bottles are produced" and "50,000 plastic bottles are recycled" next to each other, the former blinking much more often than the latter -- but the best part is "A Sagittarius named Amelia drinks a soda," just above them, mixing up the alarming and the humorous.
The other juxtapositions are just as delicious -- one birth/one death; China builds a car/Japan builds a car/Germany builds a car/US builds a car/someone else builds a car; someone buys "To Kill a Mockingbird"/someone's cat kills a mockingbird -- and so on. This being XKCD, you can be sure that Munroe has an absurdly well-thought-through process for establishing and documenting his numbers, too.
