Making an invisible Mouse?

Ok so I am making a HUD and I am using gui.EnableScreenClicker(true). Now this is exactly what I need but, is there a way of making the mouse invisible? Or if not, is there any way of making a pointer show up on the screen so you can move freely just like the ScreenClicker?

[lua]vgui.GetWorldPanel():SetCursor( “blank” )[/lua]

Thank you good sir.
