Saw this today at Moon Rhee and Heyja Do's awesome home in Brooklyn (here's their shop): a cute, little humidifier that lights up at night. A simple design that is super easy to clean, it also diffuses aromas. Multiple settings allow you to pace humidity for a long or a shorter time. In their words: "The new large aroma diffuser uses ultrasonic waves to vaporize water and the essential oil in the tank to produce a cool and dry fragrant mist."
