Show animation when databound property changess to *any* value

Question

Is there a way to attach a trigger (and a subsequent animation) to a control which has a property databound, and have that trigger fire when the value of that databound property changes (to ANY value). I don't care what value it is, I just want to show a notification when the value changes to something else.

Might be very obvious, but I don't see it.

The easiest way would be to add an extra event for this in your ViewModel that you raise manually and that you bind your EventTrigger against. You do have a ViewModel, don't you? ;)
