Not a holder, but watching with interest.

Great concept if it can make it into production.

I assume that the pixels are exposed directly to the air into which the sound is propogated (ie not contained within a box)

With these pixels being so small & moving in both directions, how does dust & grit interfere with the performance (in the real world) as opposed to a sterile lab?

How do you shield from foreign substances without it acoustically being impacted?

(Thinking more mobile ph/ lap top/ vehicles ie in a mobile environment than a static position.

First thing first, get a working prototype & demonstrate proof of concept.
