Over in the land of the rising sun plain electronic paper is so yesterday. The guys from Toppan Forms, a division of Toppan Printing, developed a paper-like product that not only includes many characteristics of paper (it's flexible and ultra thin), but which can also record and play back sound. Before you get too excited (assuming you even get excited about a talking piece of paper), note that so far this technology has only been applied to postcards being sold for about ten bucks in Japanese department stores, and with just enough room to hold up to twenty seconds of audio.
