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.
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.
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.
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.
You shouldn't cite things that you don't understand as "evidence". Take traditional Mayan belief systems for instance. They didn't involve any ideas about space travel or panspermia. The many different stories we have remaining broadly agree on a few themes that are shared with many other American cultures, namely that mankind was created by the gods out of natural materials (often corn or clay), which serves as moral reinforcement for our intimate connection to the earth.
The pleiades also weren't seen as the direction of a planet humans came from, they're just religiously important stars that may mark the date of creation. The qualifier may is used here because documentary evidence records this belief around the contact period, but it's not known whether it was believed when the calendars were initially created. The Mayans were fantastic astronomers and absolutely could have worked backwards from a later date.
I studied personally with Hunbatz Men in Mexico. Learned of the calendaring system linked to the travels of the celestial bodies and how the pyramids are 72,000 year calendars...
A centurian in the Mayan Order, studying their rites and symbolism.
Ive read many Rosicrucian Lessons, and books like that of Weed.
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.
Controlling the motion involves a lot of prediction and wave modeling, which should be a perfect application for high-performance computing.
