Seven IT wonders

Computer Closest to the North Pole:

Who's in charge: The National Oceanic and Atmospheric Administration's Pacific Marine Environmental Laboratory takes care of this floating eye at the top of the world.

Make and model: NetCam XL, made by StarDot Technologies.

Proximity to the pole: Varies. "Since the North Pole is in the middle of the Arctic Ocean, we deploy our instrumentation on an ice floe as close to the pole as we can," says Nancy Soreide, associate director for IT at NOAA's Pacific Marine Environmental Laboratory. "However, the ice floe does not stay at or near the pole. It drifts."

How it works: The webcam's container stands on a metal apparatus, on top of a piece of plywood and the ice. A battery floats beneath the ice surface, powering the webcam, which sends back pictures via satellite.
