As a final step in the minilab, we'll pull an exercise from the University of Kent. (Note that was a link to the starter code.) It involves putting together a network of processes to produce some seemingly simple output. The network, when done, should look like this:

The diagram says that the process main will have three processes running in parallel: S0, S1, and toggle. The S0 and S1 processes will output data to the toggle process, which will in turn hold one end of the screen channel.
Feel free to ask questions. I have given you minimal instruction in the language at this point. Share with other groups as you discover things, etc.
Basically, I've thrown you in the pool. See what happens.
