It's interesting because you can turn this into meter-ware (like moskito nets) and it does not need fancy materials or coating processes, just clever use of geometry.

It's not virtual analog tech scientists building a better musical instruments :)

I had no clue what a fog harp is, turns out it's used for harvesting water - interesting tech!

Nice, very practical engineering.

I wonder if arranging the stabilizing wires at an angle (instead of directly horizontal) might reduce their tendency to cling water, or could the acute angle actually make it worse? Maybe the best would be a zig-zag pattern, but that's more complex to manufacture and might be worse at holding the strings apart.
