Physics Jam/Lessons learned

1. XOs with good images for participants

We had to spend a couple of hours the first day (1) olpc-updating all of the XOs and (2) getting developers' keys on all of the XOs.

2. More organized organizers

We possibly lost interested online participants because there wasn't enough online support for the jam. Running in-person and online events in parallel requires at least 2 people (one online, one in person) taking responsibility for getting people going and helping them along.

Though, we did have a good online presence, outputting videos and pictures from the jam.

3. Git keys, good template skeletons on the ready

We had some teams using Elements (a "simplified" way of making physics scenes with Box2D) and some using pyBox2D directly (harder to get started with, but allowed teams to do more complicated things straightforwardly).
