So you thought electronic paper that resembles normal paper is all en vogue? What about electronic paper that actually
talks to you when you're touching it? Some Swedish university whizzes had the ingenious idea to equip a large billboard with a pressure-sensitive electronically conductive ink that, when it is touched, delivers embedded digital informations back via "printed speakers."

The same technology has been used in a prototype for a 'music display board.' On this slightly bowed board, a number of music albums are printed directly on paper. Just as with a regular sound system, you can sample music by touching the front of the album. The sound is then streamed right out of the paper. The board can easily be replaced as soon as there are new recordings to be marketed. This new display technology is inexpensive, combining images, sound, and space in a new an environmentally friendly way. After use, the displays can be tossed into the recycle bin.
