Title says it all 
Is there an official Processing jam of some kind or some sort of all day conference event. Would be a great way to meet other people and other educators using it in their classes and also fun!
Maybe the there is a contest to win an @shiffman autographed train whistle or something
I don’t know if there is one official gathering. There are a few.
CCFest is coming to LA in September.
Processing Community Day was in October last year and will happen again January 2019.
P5.js had their own community day.
There are probably other gatherings that I’m missing.
Libre Graphics Meeting often has some Processing related things going on (on the unofficial events front)
