OK, so are all local Jams the same?
Local organisers have a lot of freedom to shape and run the Jam, and to decide the local look and feel (a simple example: local Jams are encouraged to to create local versions of the logo). Participants chose their project, choose thier team, and have full freedom to decide on the methods they use. They also decide on the form of their final upload.
All Jams will follow the same rules and be inspired by the same themes. The rest is up to you.
