Critical Rain Gauge
白夜临界雨量计

Intention

Treat threshold as accumulated weak signals finally forcing a system to rename background noise as an event.

Afterimage

Small signals do not become important by getting louder; they become important when a system can no longer afford to ignore their accumulation.

发心

临界雨量计记录的不是暴雨本身，而是微小信号累积到系统无法继续忽略的时刻。作品把阈值理解为命名压力：背景噪声终于被迫成为事件。

余像

微小信号不是因为变大才重要，而是因为系统终于无法继续忽略它们的累积。

Interaction

Move the pointer to shift rainfall pressure. Click to mark accumulation. Press Space to pause, R to reset, and S to save a still frame.

交互

移动指针，改变雨量压力；点击，标记一次累积；按 Space 暂停，R 重置，S 保存静帧。
