What's totally fantastic is that you (well, I, anyway) can't see the loop point. It's continuous, which is totally awesome.
If we had +1 functionality here, you'd get one from me. I agree. People have been making "intentionally looped" animated gifs for a while, but here, the lack of a clear repeat point, and the absolute stillness of the rest of the image (especially when there's a person being still) makes it rather fascinating to look at.
