When the blue line moved

Both texts are newly written practice sources about an invented artwork and exhibition.

Text One: An original fictional account of viewing a kinetic artwork.

At rest, the artwork was a row of seven upright panels inside a dark wooden frame. A blue stripe crossed every panel, but narrow gaps broke it into separate pieces. Then the first panel tilted forwards. The others followed, one after another, and the stripe seemed to travel across the frame like a wave.

From directly in front, I could not see what caused the movement. At the side, however, a narrow viewing point revealed cords leading from the panels to weights inside the base. The main label described the maker's intention to suggest a wave gathering and falling. A smaller note beside the viewing point explained how the cords and weights produced the sequence.

The first sequence I watched was smooth. During the next one, the third panel hesitated while the remaining panels continued, leaving a break in the moving stripe. An attendant released the panel and reset the artwork. A visitor who arrived later saw one complete sequence and remarked that the movement was entirely dependable.

Text Two: An original record of trials carried out before the exhibition opened.

Ten visitors watched one cycle each during every trial.

Synthesise what you learn from both texts about how the artwork creates its effect, how dependable that effect is and how the display shapes visitors' understanding.
