[erlang-questions] Projects for a Hackathon

Hi Zachary,

One thing we did a number of years ago at the Triangle Erlang meetup was to
make a "game of telephone":

Everyone starts a distributed Erlang node and connects to someone next to
them. They each write a registered process that takes a message, prints it
to the console, adds their node name to it, and passes it to the next
person. When the originator receives its own message, it prints it out and
doesn't forward.

I think it's nice exercise because it teaches about the basics of message
passing between processes, constructing protocols, and standing up clusters
of Erlang nodes. One thing that was fun (and instructive) at that meetup is
that one participant changed his process to forward a different data
structure, causing the chain to be disrupted and some people's processes to
crash. One could extend the exercise to encompass more messaging patterns
like scatter-gather, etc (see the thread from this spring for ideas).
