Wiggle mouse every 14 minutes

My winXP PC at work has an enforced policy to go to screensaver every 15 minutes, requiring me to re-type my password. Highly annoying when you alternate amongst 3 PCs. Softpedia and Source Forge have "wiggle mouse" in java but I can't use it on these PCs due to problems with the java VM. Therefore I want a compiled app, with no dependencies or registry settings, that will give the mouse a slightly wiggle after 14 minutes of inactivity ( no movements of mouse or keyboard for 14 minutes). I'd like it to have a tiny icon in the system tray, but no window. A pop-up menu from the system tray icon with 2 items "wiggle mouse" which does nothing, and "exit" which quits the app.
