If you want to discuss further, send me a message on Keybase (or something else, whatever is convenient for you).

The ESP32 is pretty beefy, can you not do things on-device? I wouldn't rely on the network after what I've seen, but I haven't tried the ESP32.

My time step is constant, I have a parameter for it but I rarely change it. It's mostly a steady hand, yeah.

Are you talking about horizontal or vertical density? Vertically, the 60 pixel per meter strip is the best you can do (there are some denser ones but need a lot of current), but a diffuser will make it look much better. Horizontally, you can get very fine resolution, up to the refresh rate of the strip.
