I noticed that a mouse (above) was released recently that has an LCD click counter on the top to count all clicks by its user. I did a project (screenshot above) called Clicks in 2003 that was a software app for your desktop that counted all of your clicks, connected, and compiled them with other clicks people were making across the net through a networked app I wrote. The physical mouse isn’t networked, but that would definitely be a cool hack to try with it and connect it up to my project – ie. its physical incarnation.
