Very cool. A question about the display - it's a video image of the 
fluorescence, and the graph is superimposed on top of it?


I've forwarded this off to some friends who are working Cold Atom Lab, a 
revised version of which was just shipped up to ISS yesterday. That's 
BECs, a bit different, but subject to all the same issues ions, exciting 
them, tuning the laser, etc.
