Even though they've been way over done, I love the white twinkly lights strung everywhere at this time of year. They look especially neat twined around the trees along the center walkway of the Commonwealth Mall. When used without other distracting colored lights, and NOT otherwise, I even like to see them decorating houses as I drive past. It was maybe five or six years ago when they started becoming popular. Perhaps whoever started it got their inspiration from raindrops twinkling on a tree, like this one in City Square.
