All over the city - on blocks in my neighborhood and far from my neighborhood - I've been seeing these little sparkly mirror squares dusting the sidewalks like confetti:
I have absolutely no idea what they are and whether they are functional or litter. If they are litter, though, it might be the largest-scale litter job I've ever seen. I am so confused.
On a purely superficial level, they are kind of pretty because of their sparkle, but I don't think Wish would like to get one stuck in his paw.
Having an explanation won't have any impact on their presence, but I'm still ferociously curious. Does anyone know what these little mirrors are? Anyone want to venture a guess? Your help and/or creativity is appreciated.
