Device Orchestra is along similar lines,
with electric toothbrushes and an ever-increasing number of googly eyes:

I watched the first one: https://youtu.be/bw7ZZokxV-w
And noticed two things:
1) The intro thing with the popup requests looked very very much like the one from my link. Are they the same person?
2) The main notes seemed more like an actual instrument and didn't sound like the toothbrushes themselves. Was he cheating?

(uk.d-i-y only)

2) Yes. There's only 5 toothbrushes, so to get all the notes required
it looks like he drove them with appropriate audio instead of their
inbuilt motivators. With 5 toothbrushes you can play 5 notes at once
to make a chord.

With my link, the flatbed scanners seemed to just be driven to run their motors at different speeds, which meant that what you heard was the natural sound of the motors, but at different pitches. With the toothbrushes, it didn't sound natural. I've connected an audio signal to a motor before, and it just sounds like a crap speaker. I think it's better to hear the device making its own sound.
