You can probably do this most easily with trigger animations, but the
following VBA might be what you want. Assign the Action Settings for
your shape to either of the following macros. When you click on the
shape (in Slide Show mode), it will alternately get bigger (by a factor
of 1.5) and smaller by a factor of 1.5. Change the 1.5 in the procedures
to change the factor:
Sub Bigger(myShape As Shape)
myShape.Height = myShape.Height * 1.5
myShape.Width = myShape.Width * 1.5
myShape.ActionSettings(ppMouseClick).Run = "Smaller"
End Sub
Sub Smaller(myShape As Shape)
myShape.Height = myShape.Height / 1.5
myShape.Width = myShape.Width / 1.5
myShape.ActionSettings(ppMouseClick).Run = "Bigger"
End Sub
