From the article:
Several companies, like Seiko Epson of Japan and E Ink Corp. of Cambridge, Mass., are working on printing bendable computer displays on paper essentially computer monitors that you can roll up and fit in your pocket.
:-? How about animated banners, to be carried by protestors, etc.? Or a movie scteen that rolls up just like Grandpa's old projection screen? Or animated wallpaper for your home? A different pattern every day, if you like.
