Erik Brandal has made an electronic sound sculpture which generates square waves. So in a sense it’s a drone sculpture within a beautiful, intricate case. Here’s more from hackaday:
The heart of this sculpture is an ESP32. It’s used to generate square waves, as well as to control the filter, amplitude, echo effect and LEDs. For once I made a video of the entire building process so that I don’t have to write too much. The video itself covers everything from design, preparing the materials and soldering.
