Concentration this morning was good, I kept slipping into a moar-grinning state and managed to briefly put my attention on the good feeling itself several times.
The dev team played Whirlyball http://www.whirlyball.com/what/ in the morning. I analyzed the game and how our group of complete amateurs played it, determined my best plan was all-time-defense (no one else did this on either team ever) to block up the poachers and break up any quick point attempts, and proceeded to stop lots of the other team's potential and pick up quite a few stray balls which otherwise would have been 50/50, while lessening our offense by at most a trivial amount - 5/10 cars on offense is so clumped that 4/9 might have even been better.
At home I worked some more on the meetup plan, then Skyped with David for like 2 hours brainstorming, thinking, etc. more on what's best to do, what structure to use time-wise, etc. It was very, very productive. Like a lot. Oh and there were some things with a certain experiment but I don't know if I'm supposed to talk about it, probably not.
Now I'm off to do a bit of reading before bed, I'm being Ben's assistant for a LW post on physical intuition.
