I am familiar with VBA programming with EXCEL...which if Visio works the same way...I can envision writing a program that would draw small lines and change the color of the lines and do this continuously in a loop to make it look like the line is moving. In a way that is how one of the Powerpoint things works I looked at, you make multiple slides varying them slightly each time. That's a real possibilility. The PP may be easier than the VBA. Isn't this the same philosophy as movies?
3rd Party program...good idea too. Thanks...problem with that though, this is not something need very much don't really want to spend the $$.
3rd party engineering to do it for me...another good idea. Thanks.
