Wow, this is underrated. The start of the video cuts between a few other inventions this creator made using air. They discussed using air for digital logic gates generally.

If the active elements were convex instead of concave, I can imagine this being useful for people with visual impairments. How does this compare to existing technologies for braille displays?

The technology hasn't changed at all since the 1992 film Sneakers with the blind character Whistler. https://youtu.be/GS3npSv8iuM?t=124
