Yahoo's running this contest. Read about it here: http://yahoobingo.herokuapp.com/
This took me about 40 minutes, total. I was thinking about re-writing this in Bacon, but my Bacon is pretty raw. At best, I could propertize the cards to create a new card (i.e. a new state) every time a ball came in, but that seemed a little overwrought.
It was nice to have an opportunity to hack Coffee and Node again.
I don't know that I trust Yahoo's server. At least once I got back a "you lost" signal from the server. Since this client includes full playback of every game, I could see that I had clearly won. Unfortunately, my initial code assumed "lost" as the default state, so I couldn't see if maybe the 'won' signal was lost before receiving the disconnect. I've changed that to 'playing,' so we can see that condition now.
