Today, I found Torin Blankensmith's youtube channel, where he shows connections between MediaPipe's hand tracking solution and the TouchDesigner software that he uses to create sounds and visual displays controlled from hand movements. I think it is very impressive and nice to watch.

He even created a MediaPipe TouchDesigner plugin, that uses GPU acceleration. So I think it should have pretty low latency.

Secondly, I would like to reference this youtube short, that I found by coincidence:

I like it, because it has a similar idea like lalelu_drums: There is not necessarily a new, impressive kind of music involved. The attractive part is the performance that is connected to the creation of music. This video has 56 million views as of today, so it seems I am not the only one who finds this attractive.
