I can't find it now, but there was a youtube video of a guy building a fence to block road noise by building interlocking pottery 'bricks' with cavities that would absorb certain frequencies
helmholtz resonators, well known in acoustical engineering, also known as beer bottles and people, enough of which can significantly alter an acoustical signal.
the idea of useing specific shapes to redirect sound is new to me, but parralels how reflected coulor can work in birds and insects, where two mechanisms are employed, pigments that simply absorb(heat up) with some frequencys and reflect others, and then mechanical structures that are tuned to capture some frequencys and reflect others, producing the iridesent effects that are so attractive.
recent work has revealed that silk and artificial cloth's, can convert sound into heat quite effectivly, and other work where transparent plastic is put as an extra sound absorbing layer in windows
1. This is fantastic and a really useful set of capabilities
2. I was recently looking into vibe coding an app to generate isochrone maps with google maps API and estimated over $50 to generate the data. You're telling me that this MCP can just generate isochrone maps on demand with up to 100k data points for free? bonkers
It took me a while to find, but here is a BestOf Reddit comment from 16 years ago where a user Saydrah discusses communicating with Cuttlefish for an hour with her fingers https://www.reddit.com/r/funny/s/TBfh8u9MGX
