It can be annoying to find your mouse pointer, especially on multiple monitors. So I wrote a little tool in Delphi that moves the cursor to the center of the monitor. It’s really easy:
 Mouse.CursorPos := Point(
   Screen.Monitors[0].Left+Screen.Monitors[0].Width div 2,
   Screen.Monitors[0].Top+Screen.Monitors[0].Height div 2
 );
A couple of other lines like RegisterHotkey and a Tray Icon and it’s done.
