A Curtain that Moves to Block Peeping Toms

Self-proclaimed inventor of useless things Niklas Roy’s workshop has the unfortunate location of facing right onto the street. So people walking by constantly peer in, curiosity being a tireless master. What to do? Could pull the blind down/draw the curtains, but why do that when you can design yourself a robotic curtain with a surveillance camera, laptop, and motorized curtain rail that moves in front of anyone who’s passing, blocking their vision. Ironically it seems to arouse greater curiosity and, so, more nosey strangers. Ah well.
