What other live data is there for this?

(Besides the PNG which I am now downloading every 30 seconds using this in an empty dir:)

  while true; do wget http://www.aerospace.org/CORDSuploads/TiangongStoryboard.png -O $(date +%s).png; sleep 30; done

Seems to update every 5 minutes at the moment; I'm overengineering incase they increase it at some point.
