Light spots are the "grammatical variations" of light—they break the dullness of uniform illumination, reconstructing spatial narratives through shape, movement, and metaphor. From physical phenomena to cultural symbols, the essence of light spots lies in humanity's exploration of "the controllability of light": we can not only record the scientific laws of light spots using the principle of pinhole imaging but also employ projection technology to turn light spots into brushes of emotion. In the language of light, light spots are like punctuation marks in writing—brief pauses, strong accents, or lingering ellipses—ultimately endowing the narrative of light and shadow with a rhythm of breath. The moment a beam of light passes through a gap and casts the first light spot on the wall, humanity begins to understand that the beauty of light lies not only in illumination but, more importantly, in knowing how to "carve" through darkness.
