A simple Windows application that simulates mouse movement to prevent the screensaver or screen lock from activating. Great for making presentations or working on a computer where you have limited access to modify the screensaver or screen lock settings. Obviously, you shouldn't use this on a system where security is important. Fun fact: The original code is more than 15 years old. It has survived a transition from Subversion to Mercurial and now to Git source control.
