Sorry to lazily paste a summerizer but this is better than what I could write out..

Cymatics, the study of visible sound and vibration, explores how sound waves create geometric patterns in physical media, including glass.

This principle is suggested to have influenced the design of stained glass windows throughout history. The intricate patterns found in Gothic rose windows, for instance, bear a strong resemblance to cymatic sound patterns and often align with sacred geometry.

Similarly, Islamic geometric windows (mashrabiya) and mandala-inspired stained glass exhibit symmetrical, fractal designs that mirror cymatic waveforms.

These designs may reflect an intuitive understanding of harmonic proportions and resonant frequencies, creating spiritually resonant spaces.

The connection extends to the interaction of light and sound. When light passes through textured or stained glass, the resulting prismatic diffraction can mimic cymatic interference patterns seen in sound wave experiments.

This suggests that stained glass windows may not only filter light but also interact with sound and vibrational energy, shaping the ambiance and acoustics of a space
