This is the LYIEW SEED: an interactive ferrofluid display that reacts to your music. It comes with 10 levels of sensitivity and a bunch of buttons for easy control. It also has app control and 3 interaction modes. The ferrofluid tank is easily replaceable.
As you can see in the above GIF, the LYIEW SEED has an arcade style design. It connects to your phone via Bluetooth, so you can easily switch between different modes. This project is currently getting funded on Kickstarter.
