Reminds me a lot of Winamp that popularised such kind of music visualisations.

In the 90's and 2000's, car radios and the like had some really interesting visualizations going on. The market for radios and music installations that aren't high-end seems to have pretty much collapsed thanks to mp3 players and bluetooth speakers though. That said, there's still things like portable karaoke speakers that still come with the bells and whistles.

Amusingly I made a prototype of something similar 4 years ago during university: https://www.facebook.com/1764751847/videos/10202928199083698... It was done to promote the use of Ferrofluid for DataVis rather than a consumer product.

Happy to collab, if anyone is interested feel free to reach out... matthewmf.com

> This is called ferrofluid. It is a material developed by NASA in the 1960s. It was used as both spacecraft fuel and sealing material. I'm a bit curious how ferrofluid was used as a fuel.

It's commonly suspended in Kerosene, so maybe that's what they meant? Bit of a long stretch though.

I guess it would be easy to build a pump with it that has no moving parts.

I can't see the video, but if it's the same idea could you give some details on what you used as a suspension fluid and how you dealt with the smearing on the container?

Nice! I assume that was just ferrofluid and water?

Very cool project. There is a video of it in action[0] at the bottom. This is something that screams Kickstarter to me. [0] https://www.youtube.com/watch?v=7a3JiGTE9sc

21st century lava lamp. In that, it 100% has the chance to become an iconic consumer product.

For anyone as fascinated with this substance as I am, here [0] is a YouTube video of someone making it 'from scratch'. It's a very detailed explanation, and includes some comparisons of the outcome VS commercial ferro fluids. [0] https://m.youtube.com/watch?v=6L8yUY-doNc

There's an interactive exhibit in the lobby of the New York Hall of Science that lets you deform a blob of this shiny goo. It's a lot of fun.
