Take a regular pillow, add some LEDs and some Wi-Fi, pair it with another, identical pillow far away, and what do you have? Probably some pretty uncomfortable bedding for starters, but you'll also have the Relational Pillow, an interactive device from the minds of MIT's Ambient Intelligence Group.
The idea is disgustingly cute: One person "draws" on his or her pillow just by touching it (sensors are beneath the surface), watching the LEDs light up. At the same time, the Wi-Fi transmits the drawing to the other pillow, which can theoretically be anywhere in the world… sort of an interactive Etch-A-Sketch, but comfier.
The Relational Pillow is just a concept right now, and you can see why: Even if you could make the pillows somehow comfortable, who wants to recharge a pillow? 'Cause having the Wi-Fi always on (how else will you know you paramour is sending you a drawing) will eat it up in a hurry. Still, it might make a fun gift for couples, especially if they're semiotics majors.
