Before getting started on creating points that are animated like this using flash http://adventure.nationalgeographic.com/adventure/trips/americas-best-adventures/map/ I would like to know if it is possible in anyway to create animated point using openlayers and geoserver. If it is what are the different ways? I saw this example.
The Openlayers documentation refers to a tween function that will fire off a function every so often http://dev.openlayers.org/docs/files/OpenLayers/Tween-js.html.
Perhaps having it fire on the mouse over function and animate a circle growing around your point? I don't see why it wouldn't be possible...
