Ferrofluid visualizers and speakers are nothing new. They use a magnetic fluid that can dance to the beat of your music. They are available in various sizes and styles. This is one of the smallest ones we have tested. It doesn’t have a speaker but can react to any sound around it. It also has an easily removable ferrofluid container and backlight.
