That's a picture of my sister's flight to Phoenix (where she'll then depart from on her way to California), updated in real time. It was taken from
http://www.trip.com - they provide the serivce for free, and you can track any flight (I imagine).
The neat thing about this really is that it's updated in real-time - speed, heading, etc. The picture at the top shows how far they are along on the trip. The bigger picture actually updates every few seconds, showing how far the plane has progressed. It's all done in Java, and very nicely, I might add. So I get to watch my sister land and, later, take off again.
