The frame can hold a picture, perhaps a picture of your pet duck (For those of you who are curious what a picture of a “quack” looks like, it could be (1) a photo of an oscilloscope trace of a duck saying “quack”, where the signal input comes from a microphone, or (2) for those of you who are more scientifically inclined, a Fast Fourier Transform of the “quack” signal, or (3) a TV-huckster selling a miracle cure for wrinkles, losing weight, etc.).
