EXHIBITS: The Man Behind the Mouse
Science 303: 1589b.

Slide the cursor across a Web page and click on a highlighted word, and you've used two of Doug Engelbart's creations--the mouse and hyperlinks that direct users from one document to another. Engelbart didn't become a billionaire software mogul. But the California computer scientist's innovations while working at the Stanford Research Institute in the 1960s--which also include word processing, windows, and videoconferencing--transformed the way we interact with computers.

Learn more about Engelbart's work and ideas for the computer's future at Invisible Revolution, a growing exhibit by Frode Hegland, a Web designer and honorary research fellow at University College London, and his colleague Fleur Klijnsma. Stashed on the site are more than 5 hours of video and audio interviews with the 79-year-old Engelbart, former co-workers, and other computer worthies. For example, Engelbart explains how he got the idea for the mouse from a planimeter, a two-armed drafting instrument for measuring areas, and why he included "only" three buttons. He would have added more if there had been room.
