How the mouse works

How does the small arrow on your computer monitor work when we move
the mouse? Haven't you ever wondered how it works?

Now, through the miracle of high technology, we can see how it is done.
With the aid of a screen-magnifying lens, the mechanism becomes
apparent. Click on the link below and you will find out.

The image may take a minute or two to download and when it appears,
slowly move your mouse over the light-gray circle & also try clicking
on it, and you will see how the magic works.
