Old tech is meeting new tech with the Sustail mouse. In the olden days of technology before fancy cordless phones and non coal-powered cars, wind up technology was a big deal. Clocks and watches had to be wound up as well as little toy cars. Fast forward to 2010 and you have a wind up mouse.
The Sustail mouse is a creative concept that requires you to wind up your mouse before you use it. The mouse would be connected to your computer via Bluetooth and would have to be periodically rewound to recharge it. Ideally the rewinding would serve as a cue to take a break from the computer and rest.
The Sustail mouse is still a concept but who knows, maybe wind up technology is coming back into vogue.
