The Antikythera Mechanism, a device dated to 150 BC and recovered in a shipwreck in 1901 off the Greek island of Antikythera, predicted future positions of the moon and sun, and perhaps other planets. But that's not all: Archeologists found a tiny dial on the device labeled with the locations of Olympic games. According to the Wired Science Blog, "The feature was probably not integral to its function, but a stylish demonstration of the machine's power, not unlike a watch that displays stock prices or an iPhone-enabled speedometer."

Very impressive, but my idea of a great Olympics calendar is one that helps me keep up with a dozen or so cable channels and streaming video on websites, like the one on NBCOlympics.com. It would be even better if it hooked up to the DVR on my Cable box.

Let the games begin!
