I'm not sure what you mean.  Could you be more specific?

Is there a simple way you can modify [0] so that a pointer from main()
could be passed to vtkTimerCallback2::Execute() every time the timer
event occurs?  This is all I want to do but I am unclear on how to
register that pointer with the appropriate class.

Thanks,
~Luke
