Here is something really out-of-the-ordinary!  The details are pretty sketchy... but we now have a 'dual-cursor' mouse!

What is it ... and how does it work?

It's supposed to have a 'special' button on the side.  When you press this, a second cursor (in red color) appears on the screen, which you can use (the primary one is non-functional when the second appears)! 

When you release this 'special' button, you get control of the original cursor.

I dont know where you can use this, but my guess is that it is very useful to take 'screenshots' where you require the mouse pointer. 

For example, if you do a 'print screen' in regular Windows, you dont get the mouse pointer in the screenie.
