This is one of those cool ideas that is much easier to grasp with some animated visuals. I haven't found one for this specific application, but adjacent work in using sound to move small objects is seen at https://www.youtube.com/watch?v=XpNbyfxxkWE https://www.youtube.com/watch?v=XpNbyfxxkWE , https://www.youtube.com/watch?v=3MXVSdXZzpc https://www.youtube.com/watch?v=3MXVSdXZzpc , and https://www.youtube.com/watch?v=tzWP-NL3Lck https://www.youtube.com/watch?v=tzWP-NL3Lck Controlling the motion involves a lot of prediction and wave modeling, which should be a perfect application for high-performance computing.

In the Supplementary Materials, there's a set of example videos of this work in action. In particular, the helix shape is pretty cool to see form in (essentially) the blink of an eye.

Reminds me of Kryptonian tech in Man of Steel
- aetherspawn 4y ago
  This is exactly what this reminded me of. I can forsee high fidelity solid, textured holograms just being some kind of colour changing liquid that's controlled with sound waves. Perhaps 100 years into the future we will have dynamic furniture at a whim in our houses through some kind of similar technology .. or be able to materialize dynamic cooking pots exactly suitable for each dish, and then de materialize them afterwards (skip cleaning!), rather than store 20-odd differently sized pots.

    That’s assuming we would still have pots or a need for them with this tech.

    I was thinking maybe some day an artist could release concept album that, with a little material added in a stereo field, animates material into a 3D moving scene, like a hologram movie except with real stuff.

  When / where did you meet with Mayan Elder? Whats the story there? That sounds like an adventure!
  - samstave 4y ago
    it was an adventure. Hunbatz Men was a Mayan Elder with whom I did studies in Yucatan, specifically at Chizten Itza. He explained all the geometries to me, specifically about how the pyramid is the most advanced terminal calendar to live. Each impression on the sides represent the months The steps of the physical pyramid (the big side-walls) are representing the seasons. The small stepps (that you walk up) represent the cycles in 10,000 year steps. The inner stairs represent the oscillation over the plieades - which is where they state our DNA came from. While with the Mayan Order, the Rosicrucians and others - the mayan calendar is a representation of PanSpermia (DNA being transmitted through space) Which is how life got to earth. I know it sounds weird, but reality is not what you know. https://www.innertraditions.com/author/hunbatz-men/ https://www.innertraditions.com/author/hunbatz-men/ I have studied with many of his ilk... In'Lakech (I am another yourself)

  The anecdote about Tibet is interesting, though I couldn't find it in the book you mention. I searched for "cliff", "vibration", "sing", and a few other keywords. Do you remember more of the context? After that part, I'm afraid I don't see the connection to the manufacturing technique that is the subject of this discussion.

    There is a discussion of this in “harmony of the spheres” by Joscyln Godwin. A very well sourced book, in fact.

  Neat! The paper slightly reminds me of imagining what would happen if you tossed a big handful of dry sand into the path of the ultrasound in the product you linked.
