cool, but, while flow-based programming does has the word flow in it,
it goes beyond flow programming.

in 'fbp', there are independent programs (like black-boxes) working
as independent processes, concurrently, exchanging information by way
of "information packets" there-by liberating such a system from
typical von-neumann oriented programming limitations.
