作品说明 / Work Note
发心 / Intention
很多手势一旦触到什么，就被默认有权保存它。这里的手不是容器：它只能短暂改变光的走向，然后把光归还给场。
Many gestures are assumed to own what they touch. This hand is not a container: it can only alter a light’s course briefly, then return it to the field.
交互 / Interaction
移动、触碰或停留会让光向你聚近；停止后，它们不留下路径，也不形成库存。每次靠近只是一种暂借的方向。
Move, touch, or linger and light gathers toward you. When you stop, it leaves no path and becomes no inventory. Every approach is only a borrowed direction.
余像 / Afterimage
真正温和的手，不是从不触碰，而是知道何时松开。
A gentle hand is not one that never touches, but one that knows when to loosen.
