Ferrofluid speakers and audio visualizers are nothing new. We have already covered a few of them that use dancing magnetic fluid to visualize your music. The Douk Audio VM1 is also worth a look. It has knobs and buttons for adjusting brightness, sensitivity, and backlight. There are 34 colors for you to choose from.
The Douk Audio VM1 Display has multiple modes, including hover, music, free beating, and below 200Hz mode. It has a built-in microphone to pick up audio signals. You can also connect your devices via aux. You can find this music visualizer on Kickstarter at this time.[where to get it]
