Or, "Brian builds distributed-memory computers". Despite the misleading title, I think such a project would be a great tool for a parallel computing class. Such a machine would be roughly the same cost as a textbook and would be much more rewarding than running MPI on a multicore laptop/desktop.

Agreed. It's a really cool project, and maybe you should build one for your next parallel computing class :)
