Most people picture Antarctica as a cold place peppered with icebergs and penguins.
This is the question Tony Hansen, a lab scientist at Lawrence Berkeley, asked himself before his first trek to the South Pole a year and a half ago. Hansen's primary mission was to install air-pollution measuring devices, but he also wanted to share his Antarctic experience with colleagues and students. On that first visit, Hansen brought a Kodak digital camera to document his trip. He was able to send still images via e-mail back to his colleagues, who posted them onto a Web site. The Sphinx Pro is designed to capture both video and audio from a number of video sources, including Hansen's standard camcorder.
