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=3MXVSdXZzpc , and 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

Tea. Earl Grey. Hot.

It occurred to me last week that phrase is prompt engineering. He is giving the essential info to specify what he wants presumably because a shorter specification would yield a different result.

I wonder if star trek replicators are deterministic.

Does Picards frequent ordering of Tea Early Grey Hot make the probability of someone ordering "tea" more likely to be TEGH, and thus if Picard ordered TEGH frequently enough he would eventually be able to just say "tea"? Do replicators do continuous training or is the prompt inference engine static?
