What is a mashup, you say? This is a mashup. Innovative. Simple. Functional. User-friendly. To view pictures or videos, just click on a country (Google maps) to reveal a filmstrip view of the images (Flickr) and videos (Youtube) that are available for that country. Since all one needs to do is to tap on the thumbnail so that the video starts playing right on the map, we never even need to leave the map interface. (How nice!)
As this example reveals, there's nothing very revolutionary about mashups. The technology is there. The real ingredients comprise a pinch of creativity and a cabinet of curiosity.
