Flow path data can combine  through completeness behaviors and calculate. The movie shows a two rail flow path representing a binary value and a three rail flow path representing a trinary value combining through a completeness behavior that adds the two values resulting in a four rail quaternary sum.

The completeness behavior is derived from a transition table (truth table, function table, …) defining the output value for all possible combinations of input values.

Any table can be implemented as an completeness behavior performing calculation as data flows through the flow paths.

Oscillations, linked in arbitrarily complex structures, spontaneously oscillating can perform arbitrarily complex computations purely in terms of logical relationships: no time referent (clock), no explicit control (state machine), no special memory (registers), just animate logical structure.
