Okay, so is the ferrocell just a suspension of very tiny long and thin magnetic particles in a viscous goop?  And then all of the pretty lines are from particles lined up to reflect the light?  Or perhaps they are diffraction grating effects?  Or a combination of both?

I find it intriguing with all of the "Spirograph" images through and can't explain them.  It just feels like they are too elaborate or something.

It would seem to be similar to magnetic viewing film except for all of the pretty patterns.  And of course if you look at clips from Jason Verbelli when he plays with magnetic viewing film, he hasn't a clue what he is doing or what the patterns he sees actually mean.  What's more shocking is that he does not ask himself if he understands what he is seeing.

No matter what, I think that we would agree that Kenny is being thrown off onto a wild goose chase because he too doesn't understand what he is looking at and he has invented a "universe" to fit in with what he sees.

It's a long and winding garden path that has led into a garden maze.  I'm afraid that Kenny is stuck in the maze but he is happy to be stuck in the maze.

Yes and no.  Just tiny particles suspended in fluid, i.e., ferrofluid.  A thin layer of the ferrofluid is contained between two glass discs with minimal spacing between them.  Illumination is via a ring of LED's positioned about the periphery of the glass discs.

Pretty cool aren't they!

I agree...

Thanks for the explanations.  When you see bulk ferrofluid in action it looks like an oily goop.

It certainly makes for fascinating kinetic sculptures.

So if I understand the ferrofluid itself is magnetic and composed of long and thin magnetic particles.  I am assuming that when the layer of ferrofluid is thin enough then you can see through it to make ferrocells.

Now what happened to all the excitement in the 80s about magnetic bubble memory?  lol

These "Sixty Symbols" clips are are a series of great educational clips.

P.S.:  Okay from the clip I want to add a clarification (for myself).  The ferrofluid is paramagnetic.   So it only lines up when it is in the presence of an external magnetic field.  Take the magnetic field away and you are basically back to goop.  Add an external magnetic field and then you have the little particles in the ferrofluid aligning themselves with the external magnetic field producing all of the pretty reflection and diffraction patterns.

I suppose a ferrofluid could be formulated using particles of various shapes,  but typically the particles used are sub-micron spheroids or an approximation thereof.  The particles are typically coated with a surfactant to ensure wetting and prevent clumping within the fluid.  I have some very old ferrofluid (from the 70's) that has turned into a solid clump in the bottom of the vial.  Modern formulations are much better.  As occurs with iron filings on paper, the ferrofluid particles align with the field, and as they themselves become magnetic, they also orient and repel themselves from neighboring particles.  Very cool patterns can be generated when playing with ferrofluid.   

And yes, the layer of ferrofluid used in the Ferrocell is thin enough to be somewhat transparent. 

However, I do not understand why TK thinks that the magnet must be in motion to produce the patterns presented.
