I've recently discovered the wonders of National Geographic Magazine's website. Mainly, I found this beautiful puzzle generator. (Does anyone else have a crazy love for online puzzles? Apparently so, or they wouldn't have made this.) Also, if you're in the mood to learn something (or just prove how much you know already), here's a neat quiz on Mayan culture. It's a good way to waste time at the office and still manage to feel productive.
