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.
