This demo models how two persons, Bob and Joe, talk to eachother.

The words they are talking are the mesages.

The persons send the words at their mouth and receive it through their ears.
A timer is used to model their "think" time.

.. note:: See also :ref:`8_hello_program`, which models the same behavior with sequential programs.
