As a kid, I remember being memorized as I watched mylar strips change color as they moved in the wind.
OK maybe that was last week, seriously it’s amazing how the colors appear as if by magic.
This is “Standing Wave” by Alyson Shotz.
Much of her work is colorless, using either clear or silver materials, this work is drenched with color, but the wave is constructed from a clear material, dicroic film. It reflects some light waves and refracts others, similar to the effect on dragonfly wings or peacock feathers.
The piece changes as the viewpoint changes, which is kind of the way a wave works.
