"Of all the things that could potentially be roboticized, we can't say a curtain would be high on our list -- but then again, we're not hardware hacker Niklas Roy. In an attempt to create a \"little piece of privacy,\" Niklas developed this curtain that can watch passers-by outside (with the aid of a surveillance camera) and automatically follow them along the window to block their view inside. Of course, as Niklas notes, a sentient curtain does also have the unfortunate side effect of actually attracting the very passers-by it's trying to guard against -- such are the perils of innovation. Head on past the break to check it out in action, and hit up the source link below for all the necessary details to build your own."^^<http://www.w3.org/2001/XMLSchema#string>
