Ferrofluid Drum Synthesizer Looks Like You’re Creating A New Life Form

This is a video of a Delton8 drum and sampler synthesizer that’s been built into a custom case with the addition of a ferrofluid suspended in a clear window that moves to the beat you’re creating. That’s wild, it looks like it’s about to come to life. And maybe with a fresh beat it actually will. *beatboxing* Anything? “Just a ton of spit.” Now I’m dehydrated, tell me you brought orange slices.
