Microsoft TouchWall

"

Microsoft has an enticing alternative to the Surface called the TouchWall—a rear-projection system constructed from just "a few hundred dollars worth of readily available hardware."

TouchWall is a fundamentally simpler mechanical system, and is also significantly cheaper to produce. While Surface retails at around $10,000, the hardware to “turn almost anything into a multi-touch interface” for TouchWall is just “hundreds of dollars”

TouchWall and Plex are superficially similar to Microsoft Surface, a multi-touch table computer that was introduced in 2007 and which recently became commercially available in select AT&T stores. (Of course, TouchWall isn't exactly as cool as the Surface).

Microsoft is quick to say that they have no current plans to productize and sell TouchWall. (???!!!)
