 We observe here that each iteration of the co-fixpoint can be inductive, as it is the case in the example.
 It shows that interaction is a general process that connects entities in the environment to enable them exchanging information.
 Algorithms only process information to transform input into outputs without knowledge of the overall scheme.

 He gives the a machine that simply echoes an input stream to an output stream~\cite{wegner97} to demonstrate the power of the interaction phenomenon.
