I'd pulse the magnet so that when the music is mostly staying in the same frequency range, the fluid stays dynamic instead of standing still.
Also, if you turn the magnets off in timing with the direction shift of the music, you can basically throw and catch the fluid, instead of them always touching the ground.
for example, if music jumps from high to low frequency, you turn off the high at a certain threshold to make it all move to the left, same for up and down movement so the upper magnet turns on while lower turns off, so you throw it up in the air.
It needs additional programming to to extract a movement vector to decide the direction and timing for turning on and off the magnets to throw the fluid around, but I think it's feasible.

That top center electromagnet doesn't seem to be attracting much ferrofluid up to. I saw it pull from top left when most was lifted by the top left, but never saw it jump straight up in the center. might have just been the choice of music. Very amusing! I would do this myself if not for a lack of iron rod, a way to cut it, and a 3d-printer. and even if i had that, I'm only renting a room with no more places to keep things. Good job!

I have a question:
On my cottage i have 12v dc from solar power only. I want to have a router on the 12v system. But i think the 12v on the cottage can regulate littelbitt from 10-14v dc. Is there any device i can use that can take in: 12v dc and output: constant 12v dc?

With a more powerful MCU with higher clock frequency and support for DFT (Discrete Fourier Transform, you can get rid of the equalizer IC and have a smaller size design. But with the Arduino, that was the right choice (I never knew equalizer ICs ever existed.

You could upload a second video with short clips of copyrighted music to show it working and just let it get demonetized if it does. Or maybe upload a video with music but muted, and just add song names and a start indicator so people can sync the songs while watching.

DJ songs made by random people doesn't have content id and even not become detected by the system, the present bass frequencies results in mismatch of the music fingerprint saved in server.
So you could try one such DJ songs without copyright issue

Great project but i noticed the ferrofluid blocks most of the LED light coming from the below. Changing them on the top to light ferrofluid from the top and putting small white paper to cover the magnets, this would be even more pretty: )

Very cool project. Thank you. It might be faster to print the spools by splitting them in half and printing each side without supports. Then you could either glue them together, or to the core, or let friction do the job.

I think it would be cool if you glue 3 magnets under the fluid thingy and activate them when the specific frequency goes low so the fluid wouldn't float and slowly come down, it would make it more responsive probably.
