"Who" goes around, comes around?

Recently, I've stumbled upon an extremely well constructed visualization for migration flows inside the United States: "COMINGS&GOINGS: Migration Flows in the U.S.". It's based on December 17th, 2008 research on how people move from state to state, which states people choose to move from and which they choose to move to. For instance, you can see in the first two pictures that California has been loosing residents way faster than they've been able to get new ones. In the last two images, we can also see how the Northeast region had a much larger outgoing flow than nowadays (the opposite goes for ingoing flow), specially from/to the West).
Since the actual meaning of the data - although very interesting and well portrait - is not really this blog's main topic, let's get to business!
Colors: very well chosen, the palette complements each choice very well. Only thing that I don't like all that much, even though it's not a real problem, is the orange and green for the population movements and here is why: it gives a sensation of positive and negative reinforcements - which, by the way, are taken inversely by most of the Asian community. In the west, we tend to relate green as good and red as bad, in the east, it's usually the opposite. Conclusion: not the best choice ever, but it's not a big deal. I'd have used either blue, yellow or play with the hues.
Format: ok, not much to say here. I mean, it's the map of the U.S. - not much opportunity for creativity here, nevertheless, very well drawn!
Animation: Well timed, well designed... Basically: Well done!!!
Interactivity: Extremely well thought, although not fully explored. The hovering is so refreshingly easy and intuitive to use, but we could have some clicking involved, allowing the user to compare multiple states or regions.

Conclusion: great work! The user does not need to read the entire article to get the gist of the data. So many different views and options to play with, this could entertain you for quite a while and you learn a lot in the process!
Cuddles to the creating team!

Ok! Time for you to let me know what you think!
