Digital Ink On Billboards

cdneng2 writes "The New York Times has this article on a revolutionary new billboard. It uses digital ink, versus the typical CRT, LCD, Neon, or Plasma displays that are so prominent on the newer billboards that wastes electricity. From the article: 'By creating a paste made of tiny helix-shaped particles that can be minutely manipulated with electric charges to reflect light in highly specific ways, Magink can produce surfaces that look like paper but behave like electronic screens, rendering high-resolution, full-color images without ink - or, as Magink executives like to refer to the process, with digital ink.' The billboard can display images at 70 frames per second." You can find more articles on the billboard technology on the Magink website.
