Cute glasses that put patterns around bright points of light. Linda & Carol (my ex-wife and her wife; we went to their wedding a year ago) went to a Christmas light show. Carol collected the different types of glasses and sent them to us. So when we look through them at something with relatively bright lights, like a Christmas tree (zoom in if you’re on your phone):

Those were Santa’s, gingerbread people, and snowflakes. 😁
