This is amazing:

In the front, the display has a basin comparable to an acquarium in which Ferro Fluid can move freely. Behind the scenes powerful electromagnets enable Ferollic to influence the fluid's shape, to pick it up and move it around. Ferrolic does not produce light and is 100% silent since it does not contain mechanically moving elements. Its unique dynamics are the visual result of the black fluid continiously finding balance between gravity, magnetic fields and its own van de Waals forces.

    Eagerly awaiting the xscreensaver simulation.

    Is there nothing beyond the sorcery of magnets?

        Can't/wontfix. They were banned (FOREVER!) from the venues closest to me, for robbing the morgue and molesting the acquired corpses on-stage.

    Things I want to see:
    * the game of life
    * someone blowing smoke rings
    * Robert Patrick from Terminator 2
    * maybe a waterfall

    If only "A Sharper Image" was still in business.

    Did I read their page right? I mean, I'm American, and the swap of commas and periods in numerical figures confuses me, but SEVEN THOUSAND, FIVE HUNDRED EUROS? Like, $8,325?! I was expecting something I could examine the build of, and make, myself, for a couple hundred dollars, at most. What am I missing here? Does it need superconducting magnets and a small nuclear reactor to power them?

    • Even better, for your EUR7500, you get:

      "the lifetime of the fluids used in the glass container module mainly depends on the frequency of use. In practice this lifetime is expected to be a few months of full usage."

        All the better reason for there to be an xscreensaver version of this. Gentlemen: Start your physics engines.

      Where does the practice of using . to demarcate groups of three digits come from? It's not SI and it's needlessly confusing. Is it IPv4 hipsterism?

      • It's a little older than IPV4. It comes from the countries that use a decimal comma (vs. the decimal point used in the US and UK) to separate the integer part from the fractional part. Since the comma's taken, they need to use some other punctuation mark to separate the groups of digits. Some countries use period, some use space, some use apostrophe. The Chinese often group digits into groups of 4, the Indians can't make up their minds, the rightmost group has 3 digits, after that they use groups of two digits.

        Humans, can't all agree on even the simplest conventions.

      I can guarantee you that the time and expense to develop and build this device wasn't trivial. Just the bare electromagnets, sourced from a production-ready supplier, would run well north of a couple hundred dollars. It would be possible to make your own on a labor-of-love budget, but you would probably need to attach a stiff markup to make commercial sales worth your time.

    It strikes me that it might be interesting if this technique was used to make individual pixels instead of a giant analog-ish display.

    • Dan says:

      That's what it looks like it's doing. There's a grid of magnets behind the display, and it's turning them on and off in a controlled pattern to get the motion.

      • UnlikelyLass says:

        Sure, but what I meant was: instead of a giant tank, a grid of small tanks.

        • LionsPhil says:

          But I do love how this way it has to pick up extra ink from the reservoir at the bottom to form some numbers when transitioning from others.
