The work
Find what crosses the boundary into form.
Water changes state through nucleation and crystal growth. Temperature, impurities, surfaces, motion and acoustic energy already provide physical routes into that process. This program asks which inputs leave repeatable structural traces, which apparent traces belong to observation and selection, and which mechanisms can be engineered.
The long horizon is not a prettier snowflake. It is controlled transduction: systems capable of translating signal into useful physical change.
