MouseShade is a freeware utility that lets you to dim the screen and puts a spotlight on the area around the mouse pointer, easily guiding the audiences attention to an area of interest.
The shape of the spotlight, the colour of the shade and the opacity of the shade can all be varied by accessing the pop up menu available from the icon in the Taskbar, simply by right clicking.
When in use, the shade can be minimised, giving a clear view of the whole screen, and can then be reactivated when you need to highlight a specific part of the screen by clicking the Show option on the menu.
MouseShade is very simple to use and is an essential tool for everyone doing presentations or demos.
