In 2024 I made something similar to this for Playdate, with mirroring and dynamic pen width and dithering based on speed of movement. It is fun https://gingerbeardman.itch.io/rorschach

I tried it out on a whim and it was really fun actually.
The only immediate improvement I could think of (which may be is there in the settings) is to change the zero point so I don't have to have the camera pointed at the floor.
Edit: can "zero" by clicking "begin" with phone pointed forward.

I did NOT know the motion sensors on my phone were THIS precise, that’s surprising

The motion sensors are also usable to listen to conversations...
There was a project from 15 years ago where you could put an iPhone on a desk and if someone was typing, you could determine the keys being pressed via the accelerometer in the phone.
which reminds me of building breadboard RF sensors (using fixed caps with variable for calibrating parasitic capacitance) and since these are just oscillators you can calibrate a beat frequency (heterodyne mix) in audible range that has the theremin timbre of a squarish sine wave that you can plug straight to a speaker

It seems to make the user dance, would fun to see video of people using it for the first time. haha

I suppose this might have been done already?
change color -> put finger in front if camera
make drum sound -> tap side of phone
