I would like to use QuickTime Player to create a screen recording of the iOS Simulator running an app. I need to simulate taps on the simulator with the mouse, but I don't want the standard arrow mouse pointer in the recording. An alternate appearance of the mouse pointer (such as a circle to represent the tip of a finger) would be preferable to hiding the mouse pointer entirely (I still need to see where it is so I can use the app correctly).
What options do I have for modifying or eliminating the mouse pointer on OS X? My machine is running Lion 10.7.5.
