PointerStick

PointerStick is designed for the Windows operating system and is available to all new and existing users completely free of charge. So it is in itself a very usable and useful application that you will definitely need someday. When you go to school, the teacher also shows you things on the blackboard using the pointer he holds in his hand. And the developers themselves have moved this ruler, or rather pointer, from the teacher's hands to your computer monitors, making one realize how powerful modern technology and technology as a whole is and how they are moving forward every day.

The advantage is that a program called PointerStick doesn't need to be installed and can be run from perhaps a USB drive, which most of you will probably have. When you run PointerStick, you'll see a pointer on your monitor display just like the one you know from your teacher's hands. This is a perfect and, most importantly, usable thing.
