We had a metallic pinwheel once. It was propped up in the back yard to catch the breeze. The only problem with the pinwheel was the crazy reflections it spun around the kitchen. ...little multi colored pinpoints of light that danced and flew everywhere. It was not unlike a disco... I kept mistaking the reflections for a vehicle arriving.
After listening to me bellyache about it a few times my husband finally spray painted it black.
While a black pinwheel was less than ideal, the problem was solved. True story.
