[math-fun] (OT) Animal behavior

The recent fascinating revelations in this forum about red blood cells remind me of something I discovered only in the past couple of years. I didn't think that animal behavior was a subject that interested me that much; I still have no desire to *study* it. But (and I recommend a high-resolution TV or monitor) now that they can plant a 24/7 camera where animals live and then filter through years of footage to find the most interesting ... well, I never would have guessed how interesting this could be. (I can hardly overemphasize this.) So if you haven't already, you might like this. —Dan
