Wow, thanks for this comment. It hadn't occurred to me that you could interact with it. Neat!

I wonder if I'm just odd, or if people not realizing it's interactive is widespread.

To be pedantic you can. They would have to ship the locations along side the video.

Of course part of the art is that it is real time (ish). That may be harder to do with video. (But I guess it could be a live stream)

I just don't think the interaction is particularly valuable. I looked at the globe and hovered over one PR. Maybe I'm just not curious enough!
