Fuji Xerox plans to start selling these E-Paper Visual Index Cards sometime next year. The e-paper is ultra-thin and does not need electricity for its display, according to CNet. The article—a photo caption, really—goes on to talk about "photoconductivity seats that contain an LCD layer." I'm hoping that someone reading this can decipher what that means. All I know is, I want a stack of them.

Reader Caswal says: "The way the E-Paper works, is it requires electricity to set the image, but once it is set, it is held there by a static charge. Bit like an Etch-A-Sketch. You ground the charge to reset the screen to blank."

Reader Benjamin says: "...the photoconductivity implies that you set the e-paper down on a table and shine a negative of what you want on it and then the spots on the paper that are light have the LCD turned on and the ones that are dark don't, so you get the positive of the what you wanted on the paper."
