MEDM supports animated GIFs, where the particular frame shown is 
selected by a PV.  In fact you can use a Visibility PV on most widget 
types to control when the widget is visible or not, and then pile 
several different sets of widgets on top of each other with different 
visibility settings.

EDM can do the visibility thing, and also supports a way of defining 
your own symbols which provide a way to show an object in a number of 
different states, selecting between the states by a PV again.  This is 
probably easier to do than the visibility approach, once you understand 
how to create the symbol object.
