I came across this video in which different frequencies of sound were used to create various sand patterns on a vibrating metal plate. I was surprised by how complex some of the patterns created were! This video reminded me a lot about project 1.1 because sound was used to produce art. Although technically the art in this video isn’t an abstraction because the patterns can be reproduced with physics, I still found it to be abstract because you can’t directly tell what the pattern means just by looking at it.
