Leaf Wireless Mouse scores big time on looks and has a decent enough direction as far as tech aspects go. The one thing that we do with our mouse the most is to move it around. Based on this, the designers have created a concept that uses its motion to self-power the mouse. It sounds like a whiff of air for now, but imagine if we could have a wireless mouse that did not tank up on so many batteries every month? Because I use it so much, I tend to replace my Magic Mouse battery every 7-8 days. I say go for Leaf right now!
