The signs in the photo above aren't just signs. They're actually Yamaha speakers, made from a millimeter-thick layer of cloth. The company showed them off at CEATAC JAPAN 2009, demonstrating the prototypes as part of its booth.
There aren't many details about commercialization of the cloth speakers, but Engadget shot an interesting video of the prototypes in action at Yamaha's CEATAC booth (the source of the picture). We can't know how effective these speakers might be for very discreet home theater installations, but the technological potential is at least there. Maybe in a few years, we'll have posters of speakers that actually work like speakers, and utterly confound our friends.
