What surface engravings on PVC abstract pieces create moiré patterns under light?

Moiré patterns are captivating optical illusions that emerge when light interacts with finely engraved surfaces on PVC abstract pieces. These patterns are typically created by overlapping or closely spaced lines, grids, or repetitive geometric designs etched into the PVC. When light strikes these engravings at certain angles, the interference between the engraved lines and the light waves produces the shimmering, wave-like moiré effect.

Common surface engravings that generate moiré patterns include parallel lines, concentric circles, dot matrices, and crosshatched designs. The density and spacing of the engravings play a crucial role—too wide, and the effect diminishes; too tight, and the pattern may become chaotic. Artists and designers often experiment with varying depths and textures to amplify the moiré effect under different lighting conditions.

This phenomenon not only adds a dynamic, interactive quality to PVC art but also opens creative possibilities for decorative installations, architectural panels, and kinetic sculptures. By mastering the relationship between engraving techniques and light, creators can transform static PVC surfaces into ever-changing visual experiences.
