Map Demo on iMovie

I was reading a magazine which gave some tips for iMovie.
I had a play and discovered the map animation tool which allows you to create maps and animated journeys between two locations on the Earth.
Within a few minutes I was able to produce this example, which has obviously been reduced in quality to appear on YouTube, but the original output is HD quality video.
A few years ago, this would have cost a lot of money and taken many hours to render something like this, and it's amazing to think this is now so easy to do. Could create a range of these to fly students to the locations of the video case studies that are used in the lessons...
