While motorized human transporters have yet to truly take off, the folks over at Nissan have come up with something more practical for the time being: self-parking office chairs. With a single clap, these futuristic furniture will automagically tuck themselves back into their rightful positions, thus keeping your office or meeting room neat and tidy. And of course, it's also fun to watch, as you can see in the video after the break. Nissan says these modified Okamura chairs are actually tracked by four motion cameras on the walls, and then they are simultaneously controlled via Wi-Fi.
