The Handover Did Not Happen
Cobalt blue and acid yellow-green enter from beyond all four edges, together filling the entire viewport. They are not two objects on a background, nor is there any blank space between them into which either can retreat. The shared boundary that keeps folding toward both sides determines which side every point in the image belongs to at this moment. The short, opposing folds along the line belong to the faster rhythm: they continually push local regions back to the other side, but cannot change the overall ownership on their own.
The slower rhythm periodically exchanges most of the space. Press and hold at any height in the image, and the fast rhythm is forced to turn toward your point of pressure; it first refuses, then overshoots, returns, briefly moves in the same direction, and only then is captured there. The viewer does not drag an object, and cannot appoint a winner; they can only choose where pressure occurs, and decide how long that pressure is sustained.
After capture, release, and the next handover is canceled as a whole. The old side continues to occupy the space; the new side loses one chance to take over. The point of pressure determines where three coral seams remain, while any time beyond what capture required determines how far they deviate. These seams are not attached to the current boundary, but remain at the positions that should have been reached simultaneously, causing an event that did not happen to still occupy space.
When no one operates it, the work first performs a brief pressure that fails to capture, then completes a pressure elsewhere sufficient to cancel the handover. Mouse, touch, and the spacebar follow the same rule. The question is not whether the two rhythms can become consistent, but whether, when consistency is prescribed as the goal, the one applying pressure should also be responsible for the position it leaves behind.
