Having a street level abode can be really convenient at times, but not when it comes to privacy. Niklas Roy decided to fix that problem by installing a robotic curtain that follows onlookers passing on the sidewalk outside his personal workshop.
The system uses a security camera, a curtain rigged up with some motors, and an old laptop to provide intelligence. A full sized opaque curtain would probably provide a greater degree of privacy than this sheer little sucker, but this option is far more entertaining. [Niklas Roy via Make via Laughing Squid]
