Swiftpoint/Tech Insider
A company called SwiftPoint has designed a mouse called "The Z" that uses an accelerometer to track when you tilt the mouse, just like an accelerometer does in your smartphone. It adds a new 3D level of control to the regular mouse movements you make on a flat surface.
The Z has been on Kickstarter for about 10 days and has already nearly doubled its funding goal with 30 days left to go.
