Easey is a map animation library. It works with Modest Maps and provides advanced easing as well as inertial panning and zooming.
easey().map(map) .to(map.locationCoordinate({ lat: 38, lon: -80 }) .zoomTo(5)).run(2000);
easey().map(map) .to(map.locationCoordinate({ lat: 38, lon: 80 }) .zoomTo(10)) .path('about') .run(2000);
easey().map(map) .to(map.locationCoordinate({ lat: 60, lon: 11})) .zoom(8).optimal();
