WiggleMouse

Running a presentation can be nerve-wrecking, and the thought that your private screensaver could pop up is certainly on the list of worries. WiggleMouse is a small utility that can help you with this issue.
Basically, the program wiggles the mouse cursor at a user-defined interval. The app has a very simple interface that should be easy to figure out.
Thus, once this app is enabled, the mouse cursor should move at the interval you provided. In this way, even if there’s a big pause in your speech and you need to stick to the same slide for a longer period of time, the computer won’t be left to go idle.
WiggleMouse not only keeps the screensaver from coming on during the presentation, but also any other kind of power management tools that work on an idle timer.
The app’s interface is pretty basic and while it might not earn any prizes in the design department, it includes all the necessary elements. Thus, you can set the timer to any value you want, down to the exact number of seconds.
For instance, you can have the program move the cursor every few seconds, or once every 100 hours.
The bottom line is that WiggleMouse is a nice utility that can come in handy quite often. Inexperienced users should have no problems with running this app, thanks to the intuitive interface and overall simplicity of the tool.
