Ferrofluid displays are nothing new. We have covered a bunch them here in the past that you can interact with using a strong magnet. The LYIEW SEED takes it to the next level. It dances to the beat of your music and has app control. It comes with 10 levels of adjustable sensitivity.
This ferrofluid display has an arcade shell and removable tank. It has a couple of buttons and joystick for control. 3 modes of interaction are available (tone pickup, decompression, and interactive). The companion app lets you switch between different interaction modes.
