Here is an option for adding a little mood and character to a room. Mood Beams come in four styles and light up to add an accent to your room. They can react to sound, so set it up near a speaker for a little light show. They can also be set to one of five light shows. Mood Beams are recommended for ages four and up, and require 3-AAA batteries which are not included.
