Digital Paper created at PARC

Jesse Becker writes "Nicholas K. Sheridon, a researcher at the Xerox Palo Alto Research Center, came up with an idea for making digital paper that can hold the image, even after the power source is removed. The digital paper is erasable (a few million times), and requires almost now power to operate (a solar cell the size of your finger will do nicely). There, unfortnately, are no pictures at this URL (though there are in the print version of the magazine). "
