Only One Thing Changes: Everything else remains fixed

A system with many parts should allow more than one change. But here, it doesn’t. No matter what action is taken, only a single element responds. The rest remain fixed, unaffected, and unchanged.

Attempts to shift other parts do nothing. Different inputs lead to the same result. Movement exists, but it is always confined to one place.

Only One Thing Changes explores systems where variation is restricted to a single point. Change happens—but it never spreads, never builds, and never expands beyond that boundary.
