There are already plenty of ways to control a computer without a mouse - whether its touch-based gesture controls or the fused minds of two rats.
But this might make you want to return to the humble rodent.
The Bat Mouse is a concept design for a peripheral which floats in mid-air using magnets.
It's the work of Kibardin Design, who say the mouse would float about an inch and a half above the mousepad, and wouldn't drop all the way to the ground when in use with your hand.
No, it isn't a real product yet - and no, we have no idea if it would actually work.
But as the designers point out, there is a role here for a device which is able to treat and prevent carpal tunnel syndrome or repetitive strain injury.
