Why Does the speakers that hears birds and performance-portable Quicksort (2022)

This is the coolest thing on HN that I've seen in a long time :'). This is amazing. I wonder if this could be connected to an LLM and render images of birds differently each time? This is amazing. I want to build one. I wish I had this kind of creativity. I can do the hardware/software side, but great ideas elude me.
